e.preventDefault doesn't work with live submit

[rmurphey]

When a submit handler is bound to a form using .live(), and the submit handler includes e.preventDefault(), the form still submits when the submit event is triggered using .trigger(). When the same submit handler is bound using .bind(), the form is not submitted.

this is a dupe of #5695

[rwaldron]

Attempted same test above with:

return false;

in place of e.preventDefault();

And produced same results

Paul's cross-referenced this in #5695 so I'll close it as a dupe.
