Use WR on nightly.
Open the attached testcase
On the left there will be a dropdown. Click on that dropdown and select "40"
Wait for 20-30 seconds
AR: The tab becomes black/green/corrupted. It kind of looks like a crash, but no crash report is generated.
Prior to this regression, the page would not become corrupt.
This testcase is 100% artificial, so feel free to WONTFIX or INVALID.

It seems that crash reports were generated with swgl.

I saw the following message to logout. The STR made fallback to SW-WR and caused oom crash.

This looks like a dupe of bug 1501545 .
Depending on the code movement and heuristics, the testcase may start crashing, or get corrupted. I will dupe it to bug 1501545 , where there was some discussion on analysing this testcase.
