How are you defining "data validity semantics"?  That term is not 
present in the HTML specification.

http://www.whatwg.org/specs/web-apps/current-work/#selector-valid and 
http://www.whatwg.org/specs/web-apps/current-work/#selector-invalid (or 
if you prefer) are very clear about what :valid and :invalid are 
supposed to match (modulo 
<https://www.w3.org/Bugs/Public/show_bug.cgi?id=24165>) and they should 
be matching <form> elements that have an <input required> in them.  So 
Firefox is correct here per current spec text.

Per current spec text, looks like Chrome/IE are doing the right thing 
here, since <input type="submit"> is not barred from constraint validation.

Indeed, and since it's not barred from constraint validation it's always 
valid, modulo setCustomValidity().
