I wish sites would test their forms with popular password management systems. This kind of thing happens all too often (thought perhaps not with such a high cost). Why not make it easy for people who auto-fill with these programs -- don't fight them. (And I won't get into sites that won't let you paste passwords into their forms.)
I don’t see how they benefit real users in any way, and my password manager can’t understand it, requiring manual copy/paste entry
