I was not able to reproduce the issues on my Local machine (BigSur) using:

run-webkit-tests --iterations 1000 --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 media/video-page-visibility-restriction.html -1 -f

But, it seems the test has been flaky since it was added at https://trac.webkit.org/changeset/280298/webkit

Updated test expectations https://trac.webkit.org/changeset/280667/webkit
