According to MDN, the
form
property of an HTMLInputElement may be the id of any form in the current document or the containing form HTMLFormElement itself.The second case was previously not accounted for, only adding the submit handler when a string was present. This was breaking functionality on IE9.
All credit for this goes to @littletijn: http://git.io/vRYQX only submitting this myself as they have not responded to the issue, and (s)he doesn't look to be active.
