Attachment: Bug 1770504 - Disable test_mediarecorder_record_changing_video_resolution.html on Linux tsan/asan. r?aosmond

test_mediarecorder_record_changing_video_resolution.html is very sensitive to timing,
and tsan/asan builds plus accelerated Canvas2D can mess with the timing enoug to cause
these tests to fail more frequently.
