fast/mediastream/device-change-event-2.html

This test is a flaky failure on debug builds of macOS wk2 (mostly on x86_64 with occasional failures on arm64).

HISTORY:

https://results.webkit.org/?suite=layout-tests&test=fast%2Fmediastream%2Fdevice-change-event-2.html

TEXT DIFF (though the test seems to fail with different messages each time):

 CONSOLE MESSAGE: A MediaStreamTrack ended due to a capture failure
 CONSOLE MESSAGE: A MediaStreamTrack ended due to a capture failure
+CONSOLE MESSAGE: Error: assert_true: devicechange should only fire when the document is focused and active expected true got false
+
+Harness Error (FAIL), message = Error: assert_true: devicechange should only fire when the document is focused and active expected true got false
 
 PASS 'devicechange' event fired when device list changes
 PASS 'devicechange' events fired quickly are coalesced

REPRODUCIBILITY:

I was able to reproduce this issue constantly on macOS Ventura (13.5, 22G74/x86_64) WK2 debug at 267085@main using the following command:

run-webkit-tests --clobber-old-results --debug --verbose --iterations 50 fast/mediastream/device-change-event-2.html

REGRESSION:

I was unable to locate a regression point; however, according to the related issue, this issue (or similar) has existed since 225536@main.

Ben's above commit re-added an expectation, because this is still happening. Reopening the bug, too.
