title: Flash receives mouse events under an HTML element when opacity set
body: <p>I have an HTML document with a Flash object and an absolutely positioned HTML element above it. If I set the HTML element's <code>opacity</code> CSS property to any value less than 1, the Flash object (that is actually covered) receives mouse events. This problem cannot be reproduced with pure HTML elements. Furthermore, Flash only receives <em>hover</em> events, so I cannot click below the layer.</p>
  
  <p>I put a <a href="http://gabor.20y.hu/rgba.html" rel="nofollow noreferrer">demonstration of the problem</a> online.</p>
  
  <p>I get this behavior in Firefox 3.6, Safari 4.0 and Chrome 5.0 in both Mac and Windows. Flash plugin version 10 is installed.</p>
  
  <p>Is it a bug or the the normal <em>and</em> expected behavior? If the latter, then how can I prevent Flash receiving events when it is covered with a translucent layer?</p>
