This is new. elm dnd used to work on non-elm objects, like elm gesture layer still does. it simply used them and geometry regions on which to listen for dnd, so rage uses an evas rect for both elm gesture layer events ad well as dnd. this is specifically dnd WHILE rage plays a video. it works on the browser view as the dnd object is an elm scroller, but when in video mode there is an invisible evas rect on top for gestures and dnd.
run rage with some file e.g.:
now try and dnd anything onto it. it will do nothing. instead it will work if you do:
then dnd anything. this starts rage in browser mode instead of playing a video already.
