Hidden parts of the feed tabs and the megamenu are left out instead of hidden

A feed tab's name and the megamenu's toggle are now only rendered where they show, rather than rendered and then hidden
by a class, so nothing runs or ships for a part no one sees. The validator hint and the phone menu keep their hiding
class on purpose: the browser reveals the first, and the second is also the desktop sidebar. The house-rules checks move
to 1.1.0.
