There is an annoying bug in Chrome DevTools that people who want to impede debugging of their JS files exploit. I think it's probably related to making the regex engine use excess memory and crashing the tab.
Anyway, just mentioning it to see if someone here knows if it's a well known and difficult to fix bug, or if it's just a bit obscure to have had any fixes for.
I haven't seen that one. I'd start by searching crbug.com. Then, the first step to a fix is always to find a reproducible example of the bug. In this case that would probably be finding an example in the wild and trying to save it locally in a way that still reproduces the bug. If you can get those files attached to the bug report there's a good chance it can be fixed. When I was fixing Chromium bugs, repro cases were worth their weight in gold.
