title: A bug I am facing with JqueryUI draggable/droppable
body: <p>I would appreciate if someone can help me out,</p>
  <p>here's my code :</p>
  <pre><code>`https://jsfiddle.net/m796a3ud/`
  </code></pre>
  <p>What I want to do is drag an image from these list of Images and be able to get a clone that's draggable, and when I put it inside the box it counts how many images are inside, it works good for the most part but when I try to drag the cloned image in and out of the box a couple of times the clone gets cloned it self which is not what I want, I would really appreciate the help!</p>
  <p>thanks.</p>
