Form Submit event on iOS 8 not firing

I was having trouble attaching an event handler to the ‘wpcf7mailsent’ event on iOS 8 and older (eg: iPhone 6 Plus). After some investigation, it looks like the submit function wasn’t being called because of this piece of code in scripts.js (line 187):

$form.submit( function( event ) {
  if ( typeof window.FormData !== 'function' ) {
    return;

  wpcf7.submit( $form );
}

window.FormData is an object on iOS 8 and older so the form wasn’t calling wpcf7.submit.
I hope this can be fixed one way or another. For those looking for a temporary solution, I used a polyfill for FormData: https://github.com/jimmywarting/FormData
