 From what I can see this was changed in Opera four years ago after some  
debate [1]. The big problem was pre- and script-filled fields that  
exceeded maxlength. Users got confused when fields they hadn't touched  
threw an error. See also [2] and [3]

Sites that broke back then were: (I don't know know if any of them still  
are affected, many require login)
