Oops, fix typo blocking non-bold-or-italic Delicious font from loading

This shouldn't ever be an issue in practice? I just noticed it because
something funny is going on with the `#userbar` element specifically
not using the Delicious font, and so I figured, hey, this simulates a
very real possible scenario, I'd rather use our consistent sans font
in this case!
