:yulia, since you are the author of the regressor, bug 1247687, could you take a look? Also, could you set the severity field?

My naive attempt to extract the test case here failed, so I've asked in other channels how to do that. For now, I have a solution without the testcase.

Severity: -- → S3
Priority: -- → P3

:yulia should we consider this as a ride along for 111 dot release, or should it just ride the trains with 112?
Asking since it's a fuzzing bug, but the end-user impact is unclear

Flags: needinfo?(ystartsev)

This came up in fuzzing module workers. Those are currently flagged off for release. That said, this is shared code, and I need to check if there is a way to reproduce this on the html page loader. So far I haven't had any luck, which indicates that it is safe to ride the trains for 112. I'll update here once I hear back from others.
