Using reproduction steps above, we found that the tests were passing at 296273@main, but failed at 296275@main. Referring to the history, it is shown that the tests were failing at 296274@main. At this time, we believe that the regression point is 296274@main.

We found a second test that appears to be related to this judging by the same error message in the failure that was introduced at 296274@main:

The following logging was added in 296274@main, which validates that as the regression point for this bug:

CONSOLE MESSAGE: A capture MediaStreamTrack was destroyed without having been stopped explicitly


We will continue to add tests seen with that failure to this bug going forward.
