Legit or no? - Fighting glitched bosses.

Von leon can't attack again? or it was never fixed?

Is there any mobile boss that doesn't have a flaw in their attack script that can cause them to "glitch" and sit there without attacking? Off the top of my head Von Leon and the Ultimate Visitor both did/do it. CWKPQ we didn't really pay attention but I wouldn't be surprised if those bosses did it too.
