Attached patch is for gardening the test failures. Not sure if it's a test issue, they are also apparently failing on mac.

Gardened. Patch might still be needed.

media/media-source/media-webm-opus-partial.html is passing after LayoutTests/media/media-source/content/test-opus.webm was modified by 260822@main
Comment 7 Philippe Normand 2024-01-22 01:28:51 PST 
Only one issue left with media/media-source/media-webm-vorbis-partial.html:

EXPECTED (sourceBuffer.buffered.end(0).toFixed(2) == '1.34'), OBSERVED '1.33' FAIL
