When launching a browser on BrowserStack Live in Firefox Nightly, I'm getting a Not connected to remote machine. Trying to reconnect now... error and the JS console has the following error:

Uncaught (in promise) TypeError: RTCPeerConnection.getStats: Argument 1 does not implement interface MediaStreamTrack.

:bwc, according to the pushlog, this is one of your patches. I'm tentatively assigning this to bug 1804678, but you might know better. Any idea what's happening here?

We have good contacts to Browserstack, but I'd like to know what's actually the cause here before I try to reach out. :)

[Tracking Requested - why for this release]: Browserstack is a big application used by a lot of developers. We might be able to figure out what's going on here, and work around that, before 113 gets released, but tracking never hurts.
