Created attachment 201358 [details] Screenshot of the issue with GTK3 backend Found while testing the patch to bug 161710 When a file contains a lot of A11Y warnings, the sidebar is initialized incorrectly and can be scrolled down to show a lot of empty space. 1. Open attachment 123123 [details] (just some random file I had at hand) 2. Open the accessibility sidebar 3. Open the Formatting and then the Direct formatting categories (these are collapsed by default) 4. Grab the scroller in the scroll bar of the sidebar and scroll down -> about half way down the content of the sidebar is over and it becomes empty, but you can continue scrolling the empty space Resizing the width of the sidebar or hiding/showing it "fixes" the issue.
