title: React change custom drag image on the fly
body: <p>Is there any chance to change custom drag image which has been set in <code>onDragStart</code> event
  with <code>e.dataTransfer.setDragImage(image, 0, 0)</code> on the fly during DnD process? For example, in the <code>onDragEnter</code> ?</p>
  
  <p>Specification says, that dataTransfer has write access only for dragStart event, but may be somebody know another way to change it or set custom drag image without dataTransfer interface?
  DnD logic is required because drag process supports cross-tab   + onDrop event has a lot complex logic, so I can not simply add listener for <code>mousemove</code> event and attach image to current mouse position.</p>
  
  <p>The problem is to change drag image which  has been ALREADY set in dragStart event  to another image on  dragEnter event. I pretty sure that it is impossible by DnD API, but may be somebody had the same issue and resolved it by another way.</p>
