I was able to reproduce the timeout at TOT and at the oldest spade available (r265027) on iOS 15 simulator on my local machine using: run-webkit-tests --iterations 1000 --exit-after-n-failures 2 --exit-after-n-crashes-or-timeouts 2 --ipad-simulator platform/ipad/media/modern-media-controls/media-documents/media-document-audio-ios-sizing.html I couldn't bisect but it seems like this test was introduced at https://trac.webkit.org/changeset/214468/webkit and last modified at https://trac.webkit.org/changeset/246118/webkit Updated test expectations https://trac.webkit.org/changeset/280409/webkit Crashlog: Failed to find media engine.

The history shows that no timeouts/crash after 7/26. I will remove the test expectations and will close this bug.
