http/tests/media/hls/track-in-band-multiple-cues.html

This test is a flaky failure on all tested platforms.

HISTORY:

https://results.webkit.org/?suite=layout-tests&test=media%2FaudioSession%2FaudioSessionState.html

TEXT DIFF:

-PASS AudioSession and interruption
+FAIL AudioSession and interruption promise_test: Unhandled rejection with value: "no audio session state change"

DIFF URL:

https://ews-build.s3-us-west-2.amazonaws.com/iOS-16-Simulator-WK2-Tests-EWS/68afe987-14290/media/audioSession/audioSessionState-pretty-diff.html

REPRODUCIBILITY:

I was able to reproduce this bug on the iOS 16 Simulator running the test as follows:

run-webkit-tests --ios-simulator --iterations 50 --verbose http/tests/media/hls/track-in-band-multiple-cues.html

REGRESSION:

I was able to bisect a regression point via local testing and the flakiness dashboard. This test reproduced at 266293 at main, but it did not reproduce at 266292 at main. Changes at 266293 at main appear to be directly related to this error, and is likely what caused the failure.
