Sorry, I misunderstood - I thought the font-size was working on its own again, but like you said, it isn't.

The last thing I've been able to find is in Help:CSS and JS pages, where it says that Special:MyPage/wikia.css only affects the Default skin, but that Special:MyPage/common.css affects all skins. If trying it in there (and using debug to check) doesn't work, you may want to contact staff. Sorry I couldn't help more!
