This feature is not deployed in production anywhere yet so this is not an unbreak now. I can only replicate on beta cluster but not with safe mode ( https://en.wikipedia.beta.wmflabs.org/wiki/Albert_Einstein?safemode=1). Will look into the gadget shortly.
This seems to be intentionally added by @dmaza here: https://en.wikipedia.beta.wmflabs.org/w/index.php?title=MediaWiki%3ACommon.css&type=revision&diff=551070&oldid=548211
UBN (to me) means this should block the next train, although as this is turns out to be just an on-wiki change, that is not necessary.
Thanks - @dmaza: was this just a test (in which can it be moved to your user CSS) or part of some other task?
I'm sorry, this was my bad. It was only for testing purposes and I've reverted the edit now.
