title: Is there a way to see the stacking context, in IE/Firefox/Chrome/etc.?
body: <p>I'm trying to track down a z-index problem.  I'm looking at the page in IE9's DOM Inspector, and I just can't figure it out.</p>
  
  <p>I have one element with a z-index of 10000, and another with a z-index of 7000, and yet the z-index 10000 is drawing below the z-index 7000.  Clearly somewhere in the hierarchy, something is setting a stacking context, but I've been browsing up and down the hierarchy and I haven't been able to find it.</p>
  
  <p>Nothing other than these two elements, so far as I can see, has a z-index set.  And nothing as a opacity value set. and I'm seeing this in FF5 and IE9, so it's not the old IE&lt;7 stacking context bug.</p>
  
  <p>Do any of the browsers have a tool that will tell me which element is setting a stacking context?</p>
  
  <p>Thanks.</p>
