title: jQuery UI droppable - tolerance/greedy not working as expected
body: <p>When I drag the draggable, the element containing the droppables keeps getting triggered (because it's also a droppable), even though it's behind the droppables and they're stacked right on each other. It's behaving like there's a gap between the droppables, and there isn't one.</p>
  
  <p>I've made <a href="http://jsfiddle.net/22BsM/">an example on jsFiddle</a> and here's <a href="http://i46.tinypic.com/awyu1e.png">the screenshot of the offending behavior</a>.</p>
  
  <p>If I add padding to .parent (for example <code>padding: 0.2em 0.2em 0em 0.2em</code> the behavior is even worse.</p>
