• What is the current behavior?
  When I put dnd-droppable onto a tag, the (onDropSuccess)-event triggers when I drop a file from the File Explorer onto it, but onDragStart, onDragEnd and onDragOver never trigger.

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via https://plnkr.co or similar.
  -add dnd-droppable onto a html-tag
  -add (onDragStart), (onDragEnd) and (onDragOver) tags onto the tag and hook them up to some console logging
  -drag a file onto the tag from the file explorer (I don't know on mac, but it doesn't seem to trigger on Windows)

• What is the expected behavior?
  All these events should trigger when I drag the file on the dom element and away from it, but none of them do. Only onDropSuccess triggers when I drop the file.

• What is the motivation / use case for changing the behavior?
  I would like to monitor and change the style of the html element to encourage and inform the user that it's ok to drop the file here and thereby give further instructions in the GUI.
