Load balancers routinely botch requests for any type other than the 
specific type they're programmed to balance. There's never been an 
excuse for it in the first place (how hard would it have been for them 
to return NOERROR?), so there's no reason to expect them to treat AAAA 
any differently from other types that they don't know about.
