Apparently the empty class gets added back on somewhere, but I can't think where...
I think it's because I was passing in truthy/falsy variables instead of actual proper Booleans before - I'm fixing this in a huge rebase, it should be fixed soon.
Marking as duplicate because these should get fixed the same way. *** This bug has been marked as a duplicate of bug 55488 ***
