    This tests that we stop propagation when bubbling a submit or reset event to more than one form.  This matches Firefox behavior<br>
    This can only occur when misnested tags cause forms to be nested.<br>
    <br>
    You can manually test the submit event, but this automated test will only test the reset event.
