Native HTML modal dialogs make the rest of the page inert, so browser annotation controls could appear behind the backdrop and could not accept input. Keep the annotation overlay in the browser top layer and inside the active modal. Follow modal changes and restore the overlay after a dialog is removed and reinserted; disconnect observation on cancellation or capture.

Based on @GrannoDev's work in #16031. Preserved the original commits, merged current main, and retained the existing direction and resize handling.

Verification at fefb60a:

  • Tests added: 0 → 0. All 127 existing tests in AnnotationKeyboard, PickedElementPayload, and preview Manager pass. A fresh test agent found no meaningful additional unit test without mocking native browser behavior.
  • Desktop typecheck, targeted lint and formatting pass.
  • Headless Linux Chromium, actual base/head preload bundles with a local IPC bridge: base editor cannot receive input over showModal(); head accepts keyboard input and emits preview:element-picked with comment, selector, crop and attach submission. Verified global backdrop/dialog CSS isolation, nested/opened/closed/removed dialogs, pointer-transparent backdrops, same-task removal/reinsertion, cancellation and capture cleanup, and toolbar clicks with coordinate-based backdrop dismissal installed.
  • No native Electron, macOS, Windows, iOS or Android verification. The browser bridge proves the preload payload, not Electron IPC transport or arrival in the desktop composer. That final desktop flow remains a human verification gate.
  • Configured CodeRabbit review could not refresh this head: the original run and one later retry both hit its review quota. Its older summary is not current-head approval. Macroscope and executable CI checks pass; the quota and native composer proof remain open.
  • Independent full-diff reviews: Claude Opus 5.5 and Codex GPT-6 Sol, three rounds; the first caught page backdrop/dialog CSS leaking into the overlay, now isolated and verified; the second caught annotation clicks bubbling into backdrop-dismiss handlers, now stopped at the controls and verified. The old hide-before-reparent suggestion is redundant: browser removal steps hide the popover, and the existing show call raises it again.

Before — actual main preload; annotation field is behind the native modal:

Before: modal makes annotation controls inert

After — current head; editor is interactive above the modal:

After: annotation editor above native modal

Keyboard entry and attach recording.

Implementation: Codex GPT-6.1 Sol; tests: Codex GPT-6 Astra; reviews: Claude Opus 5.5 and Codex GPT-6 Sol. Harness: T3 Code / Codex.

Show the annotation overlay as a manual top-layer popover inside the
active native modal so its editor can receive input. Move it when dialogs
change and disconnect the observer when the annotation session ends.

Approvability

Verdict: Approved at fefb60a

Macroscope's review found this PR approvable — This is a narrowly scoped fix to keep the existing annotation UI interactive over native modal dialogs, with lifecycle cleanup and dialog-change handling contained in the preview preload. It does not alter product defaults, schemas, deployment behavior, or static-analysis configuration.

📝 Walkthrough

The annotation overlay host now uses full-viewport styling and manual popover behavior. It stops input events from propagating. When an active modal dialog is found, the host is placed inside it. A mutation observer resynchronizes placement and is disconnected during teardown.

Layer / File(s) Summary
Overlay configuration and modal placement

The host uses full-viewport styling, manual popover behavior, and a transparent backdrop. Its root stops input events from propagating. The host is placed inside a detected modal dialog or under the document element. A mutation observer resynchronizes placement and is disconnected during teardown.

Taking over this one for batch terminal-preview-03. I will update the original branch, resolve the conflict with main, and verify the annotation flow against native modal dialogs.

The takeover is published at fefb60a. The earlier ordering concern is addressed: modal changes resynchronize placement, reparenting hides the popover, and the following show call raises it. Linux Chromium proof covers a modal opening during annotation, nesting, closing, removal/reinsertion, and pointer-transparent backdrops. The before/after captures and recording are in the body. Three independent full-diff review rounds ended clean; native Electron IPC through the composer still needs a human check.

The docstring-coverage suggestion does not identify a behavior defect. The overlay lifecycle is expressed by the existing code, and AGENTS.md asks us to avoid comments that merely narrate it; no extra docstrings were added.

The previous configured review stopped at its usage limit. Please review the published head now that its reported wait has elapsed.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Find modal dialogs inside shadow roots.

If a page opens a native <dialog> inside a shadow root, document.activeElement and document.elementFromPoint() expose the shadow host, not the dialog. Both closest("dialog:modal") checks then miss it. The host stays outside the modal, so its controls remain inert. The document-level observer also misses open changes confined to that shadow root. Traverse accessible shadow roots for modal detection and observe their dialog changes. (developer.mozilla.org)
