I was able to reproduce the timeout locally on BigSur using run-webkit-tests --debug -1 --force media/video-ended-seek-crash.html --iterations 100 --exit-after-n-crashes-or-timeouts 1 --exit-after-n-failures 1 -f
Comment 4 ayumi_kojima 2021-10-27 17:36:30 PDT 
I cannot reproduce the timeout anymore after reinstalling an OS. (I had to install BigSur again on an available volume on my Mac because I started getting "No space on OS" error as I was bisecting. The test is still timing out in the history though.
