This also happens in the large text fields on our Azure Devops server

Also affecting the post editing box on https://boards.theforce.net/ (reported in #15064 originally as a single website issue but appears to be this larger bug on closer inspection).

Unfortunately I'm unable to register, or get posting privileges on those websites. Could you share any other links?
This seems to be a browser bug, but I'll try issuing a patch as soon as possible. Since our updates are being blocked by Mozilla for around 2 weeks, I'd suggest to use a Chromium-based browser in the meantime.

Thank you for the latest link, I was able to register and see the issue. There's some bug in Firefox 148, that seems to break IFrames when a style is injected (CKEditor and Google Docs use IFrames). We issued a patch, but it is expected to be reviewed in 2 weeks. In the meantime, you have to disable Dark Reader on affected websites, or use another browser.
