title: How do I prevent drop in originating container in react js and react-beautiful-dnd?
body: <p>I am using React and react-beautiful-dnd.</p>
  
  <p>This has had me stumped</p>
  
  <p>My use case is to drag items from container1 to container2.</p>
  
  <ol>
  <li>Items in Container1 cannot be dropped in Container 1 only in Container 2.</li>
  <li>If an item in container 1 is dragging the remaining items in Container 1 should not move to allow a drop.</li>
  </ol>
  
  <p>I created a sample fiddle to isolate the use case - <a href="https://codesandbox.io/s/34z92ny69p" rel="nofollow noreferrer">https://codesandbox.io/s/34z92ny69p</a></p>
  
  <p>Any help is appreciated</p>
