Unlike the failures on MacOS, the flaky failure on iOS seems to have started on around 6/30/21

I was not able to reproduce the failure on iOS 15 simulator on my local machine. The test timed out instead using:

run-webkit-tests --ios-simulator --exit-after-n-failures 2 --exit-after-n-crashes-or-timeouts 2 --iterations 500 imported/w3c/web-platform-tests/webrtc/RTCRtpReceiver-getContributingSources.https.html

Test hanged with --no-timeout flag.
