There's a cosmetic issue I've been having with the script that this update doesn't seem to have fixed: with the script enabled, even with all its features turned off, certain divs (which as far as I've found are all children of main, with both the section class and the content id) are being given the display:unset style. This 1) removes the background and 2) conflicts with the styling for .section to somehow create two bars along the left side of the element. Examples are on the "add new thread" page, the login page, and in almost every tab of the "magazine panel" moderation tool.
I tried looking for the issue in the script and couldn't find anything that jumped out at me (I... also don't know javascript, so it was a bit of a shot in the dark), but I'm as close to certain that it's this script as it's possible to be. I'm able to replicate the issue consistently across three different devices (Ubuntu/Linux Mint laptops and Android phone), running the script via the Tampermonkey extension in Firefox. (I saw that this had already been reported awhile back specifically for the login page and that you hadn't been able to replicate it, so I'm trying to provide any device-specific information I can think of that might be relevant).
Anyway, I was pushed to finally bring up the issue today because although previously the issue has just been a minor visual annoyance, I just changed the background on one of my magazines to an image and now, with the script removing the nice solid background from behind the formatting icons on the new thread page, I can barely see them. :(
