media/media-fragments/TC0003.html

Is flaky crashing on iOS 14 E Simulator wk2 Debug.

History: https://results.webkit.org/?suite=layout-tests&test=media%2Fmedia-usage-state-private-browsing.html

The crash started showing in the history on around 5/13/2021. Test results are not available before 5/13/2021.

I was not able to reproduce the crash on a simulator (iOS 15) on my local machine using run-webkit-tests --iphone-simulator --iterations 50 --debug -f --exit-after-n-failures 2 --exit-after-n-crashes-or-timeouts 2 media/media-fragments/TC0003.html

It timed out instead.
