STR: - Load https://jyavenard.github.io/htmltests/tests/mse_webm/big.html - this pages loads 5MB of webm at a time, until an exception occurs due to the source buffer throwing a QuotaExceededError Results: 10801: SourceBuffer buffered ranges grew from TimeRanges: [0.007, 545.109) to TimeRanges: [0.007, 550.11) 10801: Loading buffer: [0, 888286) 10999: got error event 10999: ok(false) should not fire 'error' event 10999: SimpleTest.finish Expected: QuotaExceededError should be caught and it should display the maximum size of a source buffer. When this happens, the video element throws a fatal error. SourceBuffer QuotaExceededError shouldn't be a fatal error.

This issue occurs because the page keeps loading the content in a loop. The initial WebM Segment contains a set length. libwebm errors when it sees content further than the initial segment length. We should ignore that length as both Firefox and Chrome are doing.
