I was able to reproduce timeout (Didn’t get the diff) on iOS 15 simulator on my local machine using:
run-webkit-tests media/track/track-in-band-duplicate-tracks-when-source-changes.html --ios-simulator --exit-after-n-failures 2 --exit-after-n-crashes-or-timeouts 2 --iterations 500

I was able to reproduce timeout at TOT, r277101 (The oldest revision found in the history), r274810 (Revision the test is last modified), and r274808 (Before the test is last modified), but I am not sure if this is the same timeout as the bot is producing since I didn’t get the diff.
