media/presentationmodechanged-fired-once.html is a flakey timeout on wk2 in iOS 14 Simulator, Catalina, and BigSur. HISTORY: https://results.webkit.org/?suite=layout-tests&test=media%2Fpresentationmodechanged-fired-once.html History indicates the first timeout occurred at r274822. TIMEOUT TEXT: -This tests that the "webkitpresentationmodechanged" event is fired only once when the browser switches back to inline from the picture-in-picture mode. +#PID UNRESPONSIVE - WebKitTestRunner (pid 78919) +FAIL: Timed out waiting for notifyDone to be called -RUN(video.src = findMediaFile("video", "content/test")) -EVENT(canplaythrough) -RUN(video.play()) -RUN(video.webkitSetPresentationMode("picture-in-picture")) -EVENT(webkitpresentationmodechanged) -EXPECTED (internals.isChangingPresentationMode(video) == 'false') OK -EXPECTED (video.webkitPresentationMode == 'picture-in-picture') OK -RUN(video.webkitSetPresentationMode("inline")) -EVENT(webkitpresentationmodechanged) -EXPECTED (video.webkitPresentationMode == 'inline') OK -END OF TEST - +#EOF +#EOF

The timeouts are not easy to reproduce, but I have been able to reproduce it at BigSur Debug ToT using the following: run-webkit-tests --iterations 2000 --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --debug-rwt-logging --no-retry --force --no-build -f --debug media/presentationmodechanged-fired-once.html The timeout does not reproduce every time the above test is run. But it's the only way I've had any success at all with reproducing the timeout. I will attempt to discover a regression point, but given the flakiness of this test, I might not be able to. But we will see.
Updated test expectation to Pass Timeout here while test is reviewed: https://trac.webkit.org/changeset/276163/webkit
I have not been able to reliably reproduce the timeouts. For this reason, I cannot discover a regression point.
Updated expectations for iOS here as well: https://trac.webkit.org/changeset/276165/webkit
