I was not able to bisect because I couldn’t reproduce the failure on the simulator (iOS 15) on my local machine using:

run-webkit-tests --iterations 2000 --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --no-retry --force --no-build -f fast/mediastream/mediastreamtrack-audio-clone.html --ios-simulator 

The test timed out and it hanged with --no-timeout flag.
