stopPropagation() for ng-file-drop to work when $document drop is disabled

I use this to prevent browser from opening file/folder preview when dropped (and navigating you away from the page)
``` javascript
 $document.bind('dragenter', function (e) {
    e.stopPropagation();
    e.preventDefault();
    var dt = e.dataTransfer;
    dt.effectAllowed = dt.dropEffect = 'none';
  });
  $document.bind('dragover', function (e) {
    e.stopPropagation();
    e.preventDefault();
    var dt = e.dataTransfer;
    dt.effectAllowed = dt.dropEffect = 'none';
  });
``` 
however it prevents ng-file-drop from working as well. Unless you add stopPropagation on the 'dragover' event.
