I believe this particular API shouldn't have changed over generations, so it's
likely something that needs to be quirked for that generation.
I haven't had a chance to check on this yet in detail though.
For now could you guys quirk this one and if I find out there was something
more systemic we can undo the quirk and do something more broad.
