    <thetext>While this test has previously been marked as a timeout on wk1 and iOS (see bug 243494), I see it as a constant timeout on Sonoma.</thetext>

    <thetext>This appears to have regressed between 268394@main and 268487@main. The only commit on this range (https://github.com/WebKit/WebKit/compare/b70eda7d68835d7dfa22e86463fbb90263b0e619...f685afa11acafdf44fd60af91b837cb1f3bf85f9) that looks vaguely related is 268412@main.</thetext>

    <thetext>We fail to get an `animationstart` event even though getAnimations() returns a CSSAnimation object as expected.</thetext>

    <thetext>We don&apos;t actually fail to get an `animationstart` event, this seems entirely tied to DOM performance.

With a debug build the call to makeDots() in the test takes about 5.5 seconds. Then it takes over 9 seconds for the `animationstart` event to be obtained. Then once we call notifyDone() it takes about 11 seconds in `TestRunner::notifyDone()` for the call to `injectedBundle.page()-&gt;dump()` to finish. Depending on how fast the system is, this ends up tallying up to over 30 seconds and for the test to time out.

With a release build, the entire test runs in about 200ms on the same hardware :)</thetext>
