On r278701 libwebrtc was updated to M92.

This caused a number of WebRTC related tests to start failing on GTK and WPE:

However, I'm unable to reproduce this failures if I run the test locally one by one.
Only when running the whole test suite this failures are reproducible (like in the bots)
This may indicate some issue caused by a previous test run that leaves WTR on an inconsistent state or something like that.

The errors the tests give look related to failure to create the SDP data channel. Examples:
