The strict answer is that it's up to the browsers; the spec allows 
browsers to do whatever they think is appropriate per their platform's 
conventions. So both behaviours are compliant.

The guidelines in the spec do not say anything about the behaviour being 
different for elements that are display:none or otherwise hidden, though, 
so I don't see any reason to consider the visibility of a button in making 
the decision as to which button is the default.
