I am able to reproduce this crash 100% of the time when using Discord and surrounding a word with _ underscores to italicize it, example this. The tab crashes immediately after I see the text become italicized.

Miko, flagging you for needinfo since this may be the testcase you were looking for.

I am able to reproduce this crash 100% of the time when using Discord and surrounding a word with _ underscores to italicize it, example this. The tab crashes immediately after I see the text become italicized.

I just tried that (in nightly and beta on macos) and I did not crash. Can you try in a fresh profile? Or tell me more about your environment so I can try to test in something closer to what you have.

I'm unable to reproduce it in a clean profile or in Troubleshoot Mode. I think it has to do with the length of time the Discord page has been open and the activity in it. I'm using 92.0a1 (2021-08-05) (64-bit) on Windows 10.

I left discord open over night, and I'm in several pretty active discords and added more activity by asking a friend to send me a bunch of messages. Still couldn't reproduce.
