This test is a constant timeout on macOS Monterey and above, debug wk1.

HISTORY:

https://results.webkit.org/?suite=layout-tests&test=media%2Fmodern-media-controls%2Ftracks-support%2Ftext-track-selected-via-media-api.html&style=debug

TEXT DIFF:

+FAIL: Timed out waiting for notifyDone to be called
 This test checks that setting an embedded text track as selected via the HTMLMediaElement JS APIs will correctly show this track as selected, and that selecting the "Automatic (Recommended)" track will revert back to selecting that entry.
 
 On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".
 
 
 PASS shadowRoot.querySelector('button.tracks') became different from null
-PASS shadowRoot.querySelector('button.tracks').getBoundingClientRect().width became different from 0
-Setting mode to 'showing' for 'English' text track via JavaScript...

REPRODUCIBILITY:

I was able to reproduce this bug on macOS Ventura running the test as follows:

run-webkit-tests -1 --iterations 10 --debug --verbose media/modern-media-controls/tracks-support/text-track-selected-via-media-api.html

It's important to note that this result differs from the flakiness dashboard, which is showing a constant crash on macOS Ventura. See bug #259545 for the crash log.
