What actually happened?
Before PR #5301, the test "buffers partial TS video segments in sequence mode" would trigger codec-switching, even though this wasn't the intent of the test. The test would consistently fail with:
Codec-switching is not a complete feature yet, with only the low-level parts of MediaSourceEngine and StreamingEngine implemented. So this is not yet urgent.
