This test has been flaky failing since being introduced on Big Sur E Wk1 around r277375, will continue to investigate.

The first failure I see on the dashboard is at r276875. 

I think this may be related to https://trac.webkit.org/changeset/276870/webkit, as the test is relying upon video.currentTime.
