Hmm. No suspect CL in range. dalecurtis@ - You're an owner here and seem to have some familiarity with this code. Could you take a look or re-assign as appropriate? Thanks!

Probably this is just ClusterFuzz getting hold of internals.* methods it shouldn't be again. I forget the bug we dupe these into, but will double check.

Correct. I did reach out to the team and there was no clear answer. I think we should remove setMediaElementNetworkState. It's used in two tests for a total of three times. We already got much more than three clusterfuzz bugs because of it :)
