This test is a flaky failure on macOS (with the exception of macOS Ventura WK1, which is a constant crash -- see related bug #259485).

HISTORY:

https://results.webkit.org/?suite=layout-tests&test=http%2Ftests%2Fmedia%2Fhls%2Ftrack-in-band-multiple-cues.html

TEXT DIFF:

 Test that multiple cues in a sample buffer are parsed correctly.
 
 EVENT(addtrack)
+EVENT(cuechange)
 EVENT(playing)
-EVENT(cuechange)
 EXPECTED (track.cues.length === '5') OK
 
 END OF TEST

I was unable to reproduce this bug on any local testing environments; however, according to the diff, I suspect that the issue is related to the test attempting to synchronously check the order of asynchronous events (i.e., EVENT(cuechange) is firing before EVENT(playing) in some instances, but the test always expects vice versa).

I have marked this test as a flaky failure while this issue is investigated. (Link: https://github.com/WebKit/WebKit/pull/16076)
