💡 What is the current behavior?

ix-event-list triggers 'no element found' warnings due to incorrect DOM querying, and non-returned promise resolve.

GitHub Issue Number: #2689

🆕 What is the new behavior?

  • returning when animated is false ensures the animation logic only runs when the user configures it to
  • Corrected DOM query ensures that the fadeOut works properly when animation is true

📝 Walkthrough

Walkthrough

The event list fade-out logic skips disabled animations and targets the rendered list container. Regression tests cover dynamic child insertion, animation warnings, accessibility, and hydration-aware clickability.

Correct fade-out targeting and regression coverage
packages/core/src/components/event-list/event-list.tsx, packages/core/src/components/event-list/test/event-list.ct.ts
triggerFadeOut exits when animation is disabled and targets div[role="list"] when enabled. Tests cover dynamic child insertion in both modes, anime.js target warnings, accessibility, and hydration-aware clickability.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: 🟡 Moderate · up to adefd

The PR fixes ix-event-list fade-out behavior, but it still lacks required release metadata and includes a test that may produce unreliable validation due to hydration timing. Merge should wait for these concerns to be resolved or explicitly accepted.

Possibly related issues

  • Issue 2689 — The change fixes the triggerFadeOut() defects described by this issue and adds regression tests.

Fix `ix-event-list` so child mutations no longer call anime.js with a missing target, which stopped the console `"No target found"` warning (including when `animated` is unset).

this has already been merged, but the text is missing a key part of the fix - the bug included that the animated attribute wasnt actually doing anything because it was not targeting the correct part of the shadow dom.
