This test is no longer crashing but it's still flaky (failure, timeout, pass) for iOS and also Mac:

https://results.webkit.org/?suite=layout-tests&test=http/wpt/mediarecorder/mute-tracks.html&platform=mac&platform=ios

This bug ticket is still referenced in iOS' TestExpectations to track the status of this test (even though this ticket is closed):

https://searchfox.org/wubkat/source/LayoutTests/platform/ios/TestExpectations#3320

Perhaps it's worth to update the expected results for this test and reopen this bug.

For WebKitGTK and WPE the test is still a flaky crash. Reported at:
