The WPT test at imported/w3c/web-platform-tests/web-animations/interfaces/Animatable/animate-no-browsing-context.html is failing reliably, flaky or timing out.

This still happens, but it's expected as we do not fully support mutable timelines, much like other browsers at this point (there is a feature flag for this).

We have support for mutable timelines now, but we still fail the "Replacing the timeline of an animation targetting an element in a document without a browsing context leaves it in the pending state" test because we don't have any logic that checks an element can actually be rendered to resolve its ready promise.
