Linux Firefox Isolated Web Container Mem Leak? (beehaw.org)

Good day all. I'm on Fedora 38, firefox-114.0-1.fc38.x86_64. Whenever I go to beehaw it seems that the Isolated Web Container just starts consuming my entire ram, then swap, essentially halting my system.

That other site listed issues, but they're all private now. Anyone else hitting memleaks with the isolated web containers?

I do have quite a few extensions, but I was hitting this even in private browser mode with the extensions off and Chromium doesn't appear to suffer any issues.

So I'm thinking this is a memleak int he firefox Isolated Web Containers.

EDIT: Just tried downgrading to firefox-111.0.1-1.fc38.x86_64 and while the Isolated Web containers does take up a lot of memory is seems to balance out.

I also noticed this last night on Pop! OS. Noticed it nearing max- with 32gb of RAM, when my system fans spun up out of the blue. Closing my tab released all the memory. Does not appear to affect the machine I'm using currently though, which is odd- Linux Mint, same Firefox version.
