LT is not enabled on the GitHub web editor

I switched to using LanguageTool from Grammarly recently. I pretty quickly noticed that it does not seem to activate inside the GitHub quick web editor. Which Grammarly did.

Reproduction:

1. Get any file on GitHub
2. Click on the 3 dots next to the file
3. Click on "edit file"
4. LT will not seem to activate

LT isn't active on Github, as the editors often contain source code which LT cannot check properly.

It works for me on GitHub. Just only on the comments, issues and pr creation/edit
