🐛 [Bug] No page scrolling and gray page overlay when creating a post

🐛 Bug Report

When I write a post and add a link to the post, often times the windows is blocking me from being able to scroll the page or or down, after I've added a link. The whole page gets a transparent gray overlay and only reloading the page helps to get out of that mode. I can still write and click on links, but I can't scroll anymore. Pressing the ESC key on the keyboard doesn't help.

I can't reproduce this very well. It just appears to happen randomly. Sometimes after a while of editing a post. Sometimes I only add a picture to the post and the title but nothing in the body of the post. It has happened on my todays post.

This is Firefox 92.0.1 on Linux Mint.
