title: Greedy not capturing the first event
body: <p>I have a jsfiddle here - <a href="http://jsfiddle.net/xVvZB/1/" rel="nofollow">http://jsfiddle.net/xVvZB/1/</a> - with two overlapping beige boxes that are droppable and a red box to drop onto the beige boxes. Even though I have "greedy" set true in the beige dropOps:</p>
  
  <pre><code>var beige_dropOps = {    
      drop : beigeDrop,       
      accept : '#redBox',     
      greedy : true
  };
  </code></pre>
  
  <p>when the redBox is dropped on  them I get two calls to the drop handler, one for each beige box. So it appears that the drop event is not being captured by  the top box, as I expect with greedy = true. You can see the two interrupts by turning on Firebug and watching the debugger line in beigeDrop() gets called twice, once with this=box1 and once with this=box2.</p>
  
  <p>Does anyone know what's going on?</p>
  
  <p>Thanks</p>
