title: IE10 hover pseudo class doesn't work without background color
body: <p>I have a div <code>position:absolute</code> over a canvas tag. The div uses the hover pseudo class to set <code>overflow:visible</code> to create a simple popup-type effect. In Chrome, this works fine. In IE10, the hover pseudo class is only activated when I'm hovering over an element within the div or if I give the div a <code>background-color</code>.</p>
  
  <p>Any help is appreciated!</p>
