[whatwg] UA validation and the submit event

Kayak.com is in trouble because they've set a maxlength that is 
smaller than some of the data the script sets input value to. (I'm 
sending them some feedback about that). However, the site shows an 
interesting problem: the UA (testing in Opera 9) does not submit the 
form because of the validation problem, but the onsubmit event has 
been called, meaning the site has disabled its submit button. Hence, 
the user has no way to fix the data and resubmit (even if she 
actually understands what the error is).

Should we really fire onsubmit if the UA prevents submitting the 
form? Button-disabling-on-submit scripting isn't exactly rare..
