Single post in Quality of Life changes [UserScript]

Just stumbled upon something of an amusing bug: The added boxes for Search and Sort in the shelter randomly showed up in my signature. As far as I know, this Trade Forums post is the only one this has happened to, so it may be to do with positioning relative to the code? Or something? It's not that big a deal, even faintly amusing, but I should probably still report it. Has anyone else gotten this?
