Can repro on a build from Jan2022, so not a new regression
Can repro with sw-wr, so probably not related to drivers.

To be clear, this has been present in Firefox in some form since 2019 or so. I dont think this has any significant end-user impact, or else we would have known by now. The STR are very edge-case, i imagine.
This should be a low priority bug.

I agree with :mayankleoboy01, this doesn't seem to be a priority, primarily because the impact seems to have been largely unnoticed for years. Classifying as S3 for now, but this may actually fit the description of an S4.

You dont need to tear the testcase. Just drag it on the tab-bar, and the error will appear.
