Hello Benjamin! As the owner of this component, could you please help us assign the bug to someone?

Thank you!

FWIW, the recent errors here are all on the new http3 configuration, so it could be disabled there if the failure rate is an issue.

This is frequent: https://treeherder.mozilla.org/jobs?repo=mozilla-beta&group_state=expanded&resultStatus=pending%2Crunning%2Csuccess%2Ctestfailed%2Cbusted%2Cexception%2Crunnable&searchStr=linux%2C18.04%2Cx64%2Cwebrender%2Cdebug%2Cmochitests%2Cwith%2Chttp%2F3%2Cserver%2Ctest-linux1804-64-qr%2Fdebug-mochitest-plain-http3%2C7&revision=54abc3457714a3aac7326b65e2adfa8e828a2382&selectedTaskRun=VJGVdzxBQKyvhEOyVLYFZw.0
It seems to affect only Linux 18.04 x64 WebRender debug Mochitests with Http/3.
I guess we could disable this for now? as you said above, Andrew.

I don't have any particular opinion about these tests, but it seems reasonable to me to disable them with http3, as they'll be running in other configurations, and bvandersloot can take a look when they have a chance.

Taking myself- Disabled for http3 is fine for now.
