 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)

The YaBB forum software
SuperOffice eJournal (a support system Opera used)
http://kayak.com/ (was fixed after we pointed it out)
http://www.costco.com/ (internal navigation)
http://www.nowwhere.com.au (zooming maps)
