Hello! I have managed to reproduce the issue using firefox 121.0a1(2023-11-09), 120.0b9 and 119.01 on MacOS 12.6, Windows 10 and Ubuntu 22.04. I will set this issue as NEW and update the flags in order get our developers involved.

Have a nice day!

It looks like these kind of Github pages are using a technique to only render elements in the viewport, so when we capture the full page, we get the correct document height but there are gaps where github hasn't rendered content it thinks if out of view.
