title: Jquery Animate Issue with Draggable Item
body: <p>I have a jquery script to swap draggable items locations but for some reason the animate effect causes visual issues during the swap. The script is a variation of codef0rmer's jsfiddle that I've made a few changes to to fit my needs. I created a jsfiddle to show the issue, currently I've located the problem coming from the swap function and have commented out the line that works but doesnt animate. If anyone can help me with getting the swap to animate correctly I'd greatly appreciate it. You can view the jsfiddle here: <a href="http://jsfiddle.net/AywmJ/161/" rel="nofollow">http://jsfiddle.net/AywmJ/161/</a></p>
  
  <p>This is function that the issue is originating from (I believe):</p>
  
  <pre><code>  function swap($el, fromPos, toPos, duration, callback) {
             $el.animate({fromPos, toPos}, duration, callback || $.noop);
             //(callback || $.noop)();
          }
  </code></pre>
