There is a  <use> element references a <rect> element, the <use> element has a mousedown event and <rect> element has a mouseover event.
The mouseover event on <rect> element changes its own color. When the <rect> element's color changed, the mousedown event on <use> element 
can't be fired.

Safari, Chrome, and Firefox all agree on rendering for this test case. I don't believe there is any remaining compatibility issue.
