Since 272844@main, we allow MediaStreamTrackPrivate to work out of main thread. It made ASSERT(isMainThread()) to fail in many tests.

Why is gardening still done on this bug? Are the ASSERTs still an issue?

These ASSERTs are fixed. And we don't do gardening on this. Looks like, Diego re-opened it to push one land a related PR.
