WE DON'T CARE.
Clearly the problem is way too difficult for addon authors to figure out, because here we are, ten months after the release of 2.0.1 (which introduced this breakage), and it STILL happens.
Blizzard needs to either ensure that this never happens, or put in a detector that tells the ordinary user "hey bozo, addon XYZ just broke your pet bar", and that also tells the developer "hey moron, your addon XYZ did ABC at line 123 and broke the pet bar, so stop doing that you idiot"
Because clearly we are all too stupid to comprehend the brilliance that is the 2.0 pet bar behavior.
