Here is a reduction (bugzilla won't accept it as an attachment right now):

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="100px" height="100px">
  <defs>
      <rect id="target" />
  </defs>
  <use id="test" xlink:href="url(#target)"/>
    <script>
    document.getElementById("test").instanceRoot.addEventListener("mouseover", function() {}, false);
    </script>
</svg>

Mitz, could you retest in ToT? I can't reproduce it, but like to hear your opinion before closing.
