Found another error, missing comma in MediaWiki:Common.js/Usertags.js here: UserTagsJS.modules.custom = { 'BLACK OUT': ['technician'], 'Guppie the Third': ['technician', 'wasfeatured']

But actually I don't see a background defined through CSS, so you're probably right, I guess it's another part of the bug. You could set it through CSS manually pending a fix, if you want.
