On the posting page, if you open "Font Size", select a size, then click on "Font Family" to select a family (or vice versa), it opens the other one.
What I mean is that if I click on "Font Size" to close it, it'll close "Font Size", but "Font Family" will open. Closing "Font Family" will make "Font Size" open. And so on and so forth. Not a big bug, just kind of annoying.
I've put a fix in for just this forum so far. If someone wouldn't mind doing a hard refresh (just press Ctrl + F5 on your keyboard) and testing that it's no longer happening that would be great
