I have updated the expectations for this test here:
https://trac.webkit.org/changeset/274545/webkit
Comment 3 Robert Jenner 2021-03-16 18:41:49 PDT 
I have reproduced the timeout at ToT for macOS release using the following test:

run-webkit-test media/media-fullscreen-return-to-inline.html --iterations 1000 -f

I cannot reproduce the text failures because those only occur on an Apple Silicon Mac, and I do not have access to one.
