The timeout only occurs on Apple Silicon Macs, and as such I cannot reproduce the timeout because I do not have access to said system. 

For what it's worth, the test appears very very flakey in the history, and the timeout rarely occurs. For this, I have updated the test expectation for Pass timeout while the test is reviewed here:

It appears this isn't just occurring in Debug. I have removed the debug flag to include BigSur Release as well here:

I've also related this bug to a different bug regarding webrtc because they may be similar.
