title: document.onmousemove not firing over a embedded pdf object
body: <p>I have a PDF document embedded in div in a page. The page also has re-sizable regions to make one column smaller/larger than another on demand. </p>
  
  <p>When re-sizing the regions, onmousemove events are not fired when the mouse is over the pdf, thus breaking a lot of the re-size functionality.</p>
  
  <p>Any way to get these onmousemove events?</p>
  
  <p>Thanks!</p>
