<p>This test ensures that multiple form submission protection is correctly reset on mouse events. To test manually:
<ol>
<li>Click on "Click 1" to submit form to a new window. The window will close immediately.
<li>Click on "Click 2" to submit form to this window. Single word "SUCCESS" should replace the contents of this document.
</ol>
<p>If either event doesn't occur, the test has failed.
