Issue details

On Android, when a RefreshView wraps a WebView whose inner HTML contains a scrollable element that is pre-scrolled away from the top, pulling down inside the WebView incorrectly triggers the pull-to-refresh indicator even though the inner content has not yet reached the top. The expected behavior is that the RefreshView should only refresh after the user has scrolled the inner content all the way to the top and then continues pulling downward.

This issue is specific to cold-start or root/startup page scenarios where the WebView source is loaded before the native view is fully attached to the window hierarchy, and does not reproduce in navigated pages within the HostApp environment.

Root Cause

The issue occurs because of a timing mismatch between Android's addJavascriptInterface registration and the WebView page load sequence. Android only exposes a JavaScript interface to pages that begin loading after the interface is registered. The original code deferred Attach to OnAttachedToWindow, which works for normal navigation but fails in cold-start scenarios where Source is set before the view enters the window hierarchy.

In that case, the page loads before OnAttachedToWindow fires, leaving window.mauiRefreshViewHost undefined in JS, scroll state is never reported, CanScrollUp stays false, and SwipeRefreshLayout incorrectly triggers pull-to-refresh on every gesture.

Description of Change

The fix involves moving Attach(this) into the MauiWebView and MauiHybridWebView constructors, guaranteeing the JS bridge is registered before any page load regardless of lifecycle timing. Since Attach is idempotent, the existing OnAttachedToWindow call becomes a harmless no-op. To prevent unnecessary JS overhead on standalone WebViews, OnPageFinished now checks IsInsideMauiSwipeRefreshLayout before injecting the rAF polling observer, and OnAttachedToWindow calls Detach() when the WebView is not inside a RefreshView, removing the bridge for standalone WebViews after window attachment.

Why Tests were not added:

Regarding the test case: The HostApp always navigates to test pages at runtime, so OnAttachedToWindow is triggered before MAUI calls LoadDataWithBaseURL, and the JS bridge is registered correctly. However, in cold start or root page scenarios such as the Sandbox, the page loads before OnAttachedToWindow, causing the bridge to register too late and making window.mauiRefreshViewHost unavailable in JavaScript. Since the HostApp does not reproduce this lifecycle order, the issue can only be verified manually using the Sandbox sample and cannot be covered by HostApp UI tests.

Tested the behavior in the following platforms.

Android
Mac
iOS
Windows

Pre-Flight — Context & Validation

Issue: #35572 - [inflight regression] Android RefreshView incorrectly refreshes when pulling inside a pre-scrolled WebView internal scroll container
PR: #35633 - [Android] Fix for Android RefreshView incorrectly triggering pull-to-refresh when scrolling inside WebView or HybridWebView on cold-start
Platforms Affected: Android
Files Changed: 6 implementation, 3 test

Key Findings

The bug is Android-only and involves RefreshView wrapping WebView/HybridWebView content with an internal HTML scroller that is already scrolled down; RefreshView refreshes before that inner scroller reaches the top.
PR fix registers mauiRefreshViewHost in MauiWebView/MauiHybridWebView constructors so Android exposes the JS bridge before cold-start page load, injects the observer only while hosted in MauiSwipeRefreshLayout, and adds touch interception ownership in MauiSwipeRefreshLayout.
Gate artifact already reports PASS: without fix, WebView_HasScrollCaptureBridge_AfterConstruction and Issue33510 fail; with fix, both pass. Gate verification was not re-run.
Prior inline review concerns covered transient detach/re-attach bridge loss, MOVE fallback when JS had not reported state, and UI test assertion timing. Current revision adds deferred detach, MOVE fallback, and a revised test path; latest code-review found no actionable code issues.
Impacted UI categories recorded by prior detection: RefreshView, ViewBaseTests.

Code Review — Deep Analysis

Code Review — PR #35633

Independent Assessment

What this changes: Adds Android RefreshView/WebView scroll-state capture via a pre-registered JS bridge, lifecycle detach handling, gesture arbitration, and regression coverage.
Inferred motivation: Prevent RefreshView from intercepting pull gestures while WebView/HybridWebView internal HTML content can still scroll upward, especially during cold-start/root page loading.

Reconciliation with PR Narrative

Author claims: Bridge registration was too late for cold-start pages; constructor registration plus scoped observer injection fixes it.
Agreement/disagreement: Code matches the claimed root cause and approach. Existing review concerns about transient detach and MOVE fallback appear addressed.

Findings

No new concrete code findings. Expert reviewer returned no inline findings; inline-findings.json was written as [].

Devil's Advocate

The Android WebView lifecycle is subtle, and I cannot empirically verify cold-start/Shell transition behavior here. CI is currently red (Build Analysis, maui-pr-uitests, maui-pr-devicetests), so this should not be treated as ready until failures are resolved or classified unrelated.

Verdict: NEEDS_DISCUSSION

Confidence: medium
Summary: Code review found no actionable code issues, but failing CI prevents LGTM under the skill rules. Human/CI follow-up is needed before merge readiness.

Fix — Analysis & Comparison

Fix Candidates

#	Source	Approach	Test Result	Files Changed	Notes
1	maui-expert-reviewer	Native WebView gesture ownership in `MauiSwipeRefreshLayout`; no JS bridge reliance.	❌ FAIL	2 files	Failed `WebView_HasScrollCaptureBridge_AfterConstruction`; abandoning constructor bridge cannot satisfy cold-start gate.
2	maui-expert-reviewer	Constructor bridge plus JS-driven transient `CanChildScrollUp()` block on nearest `MauiSwipeRefreshLayout`; no parent `OnInterceptTouchEvent` gesture state.	✅ PASS	7 files	Passed device WebView and UI `Issue33510`, but not clearly better than PR due async JS-to-parent state, stale-block, multi-WebView, and cancellation risks.
3	maui-expert-reviewer	Constructor bridge plus child-owned DOM gesture gate using `RequestDisallowInterceptTouchEvent` from bridge callbacks; no parent `OnInterceptTouchEvent` state or parent scroll block.	✅ PASS	7 files	Passed device WebView and UI `Issue33510`, but not clearly better than PR due JS timing and ancestor-intercept fragility.
PR	PR #35633	Constructor bridge, scoped observer injection, deferred detach for transient reattach, and `MauiSwipeRefreshLayout.OnInterceptTouchEvent` ownership using cached JS/native scroll state.	✅ PASSED (Gate)	10 files	Original PR; remains selected because it passes gate and has fewer timing-sensitive JS-to-parent interactions than passing alternatives.

Cross-Pollination

Model	Round	New Ideas?	Details
maui-expert-reviewer	1	Yes	Native-only parent gesture ownership; learned it cannot satisfy constructor bridge gate.
maui-expert-reviewer	2	Yes	JS-driven parent `CanChildScrollUp()` block; passed tests but introduced parent stale-state risks.
maui-expert-reviewer	3	Yes	Child-owned DOM `RequestDisallowInterceptTouchEvent` gate; passed tests but introduced JS timing/ancestor propagation risks.
maui-expert-reviewer	4	No	Meaningfully different approaches were exhausted: native-only fails gate; two JS-driven alternatives pass tests but are not demonstrably better than the PR's native parent-intercept state machine.

Exhausted: Yes
Selected Fix: PR's fix — It already passed the gate, and the passing alternatives are not demonstrably better. Candidate 2 and 3 validate that other strategies can satisfy current tests, but both move more correctness into asynchronous JavaScript gesture callbacks and add stale-state/timing risks that the PR's native interception path avoids.

try-fix-1/content.md: native-only approach, failed device gate.
try-fix-2/content.md: JS-driven CanChildScrollUp() gate, passed device and UI tests, not selected.
try-fix-3/content.md: child-owned DOM gesture gate, passed device and UI tests, not selected.

Report — Final Recommendation

Comparative Fix Report — PR #35633

Candidates compared

Rank	Candidate	Test result	Assessment
1	`pr`	✅ Passed gate	Best candidate. It fixes constructor-time JS bridge registration, scopes observer injection to RefreshView hosting, preserves the bridge through transient detach/re-attach, and handles gesture ownership in native `MauiSwipeRefreshLayout` state.
2	`pr-plus-reviewer`	✅ Passed gate	Equivalent to `pr`. Expert review produced no actionable inline findings, so no sandbox changes were applied; ranked immediately after `pr` only to make the single selected winner explicit.
3	`try-fix-3`	✅ Passed device WebView and `Issue33510` UI tests	Functionally viable in the tested scenarios, but more fragile than the PR because it relies on JS touch timing and `RequestDisallowInterceptTouchEvent` propagation across ancestors for gesture ownership.
4	`try-fix-2`	✅ Passed device WebView and `Issue33510` UI tests	Functionally viable in the tested scenarios, but less desirable than the PR because asynchronous JS callbacks mutate parent RefreshView suppression state and introduce stale-state, multi-WebView, detach, and cancellation risks.
5	`try-fix-1`	❌ Failed regression tests	Ranked last because it failed `WebView_HasScrollCaptureBridge_AfterConstruction`; candidates that fail regression tests must rank below candidates that pass.

Comparative analysis

try-fix-1 is eliminated because it failed the regression gate. Its native-only gesture ownership idea could prevent some parent interception, but it abandoned constructor-time JS bridge registration and therefore does not satisfy the cold-start requirement.

try-fix-2 and try-fix-3 both pass the recorded Android regression tests, but each shifts more correctness into asynchronous JavaScript-to-native gesture callbacks. try-fix-2 blocks CanChildScrollUp() via parent state, which creates additional stale-block and multi-WebView edge cases. try-fix-3 lets the DOM observer call RequestDisallowInterceptTouchEvent, which is more sensitive to early MOVE events, cancellation, multi-touch, and ancestor propagation.

The PR fix passes the gate while keeping the crucial constructor bridge registration and using a native parent-intercept state machine for gesture ownership. The expert reviewer found no actionable issues, making pr-plus-reviewer identical to pr; because there is no diff between the top two candidates, the raw PR candidate is selected as the winner.

Winner

Selected candidate: pr

The PR is the single winning candidate because it passed the regression gate, has no actionable expert-review findings, and is less timing-sensitive than the passing try-fix alternatives.

Tests Failure Analysis

@BagavathiPerumal — test-failure review results are available based on commit 3baf2c6.
To request a fresh review after new comments, commits, or CI runs, comment /review tests.

Test Failure Review: Likely unrelated - click to expand

Overall verdict: Likely unrelated

All three distinct failures are on Windows and macOS platforms; this PR changes only Android code. Both maui-pr-devicetests and maui-pr-uitests have been failing on main continuously (5 consecutive failures each), confirming pre-existing infrastructure instability rather than regressions introduced by this PR.

Failure	Verdict	Evidence
maui-pr-devicetests — Run DeviceTests Windows	Likely unrelated	Helix work items `Controls.DeviceTests-packaged` and `Controls.DeviceTests-unpackaged` failed on `windows.11.amd64.client.open` (job `97b5145c`). PR touches only Android files; all Android, iOS, and Mac device tests passed. Main branch builds 1459940, 1455022, 1454817, 1451776, 1448204 all failed for the same definition.
maui-pr-uitests — macOS UITests Controls CollectionView	Likely unrelated	Job cancelled after exceeding 180-minute limit on agent Azure Pipelines 180. PR does not touch CollectionView. Main branch builds 1455207, 1454908, 1451775, 1448203, 1446888 all failed for the same definition.
maui-pr-uitests — macOS UITests Controls Shell	Likely unrelated	Job cancelled after exceeding 180-minute limit on agent Azure Pipelines 188; test results published (run `4030123`) show 1 non-flaky failure but PR changes no Shell code. Same pre-existing base-branch failure pattern.

Recommended action

No action needed on the PR side. The Windows device test and macOS UI test failures are pre-existing on main; the primary maui-pr build passed and all Android-platform test jobs succeeded.

Evidence details

PR scope: 10 files changed, all in src/Core/src/Platform/Android/ and Android-specific test files. Labels: platform/android, area-controls-refreshview. Primary build (maui-pr, build 1455512) passed.

Windows device tests (build 1455950):

Helix job 97b5145c-2d23-4d1e-928d-67d525474ef7 on windows.11.amd64.client.open completed with 13 work items; work items Controls.DeviceTests-packaged and Controls.DeviceTests-unpackaged reported as failed.
Helix console log returned 404 (unavailable); specific test names within those work items could not be confirmed.
All other device test stages (Android CoreCLR, Android Mono, iOS Mono, MacCatalyst Mono) passed.
Recent maui-pr-devicetests main-branch builds: all failed (1459940 on 2026-06-11, 1455022 on 2026-06-08, 1454817 on 2026-06-08, 1451776 on 2026-06-08, 1448204 on 2026-06-03).

macOS UI test timeouts (build 1455949):

macOS UITests Controls CollectionView: job timeout after 180 minutes (Azure Pipelines 180).
macOS UITests Controls Shell: job timeout after 180 minutes (Azure Pipelines 188); Publish the mac_ui_tests_controls test results task reports 272 results published (test run 4030123) with 1 non-flaky failure, but specific test name not extractable without authenticated AzDO test API access.
Android, iOS, and WinUI UI test jobs all passed.
Recent maui-pr-uitests main-branch builds: all failed (1455207 on 2026-06-09, 1454908 on 2026-06-09, 1451775 on 2026-06-08, 1448203 on 2026-06-04, 1446888 on 2026-06-03).

Limitations: No AzDO bearer token was available; authenticated _apis/test queries were skipped. The specific failing test names within the macOS Shell run and the Windows Helix work items could not be confirmed without authenticated access. Build Analysis check is derivative of the above failures.

Can you please resolve conflicts?

…ure for MauiWebView and MauiHybridWebView by moving Attach to constructor, detaching bridge for standalone WebViews, adding IsInsideMauiSwipeRefreshLayout guard in OnPageFinished, and adding constructor bridge attachment device test.
