Dragging image2 without caption fires paste event

[Alfonso Martínez de Lizarrondo]

Using Firefox (other browsers untested), open ​http://ckeditor.com/demo#widgets and set in the console a listener for paste:

CKEDITOR.instances.editor2.on('paste', function() { alert("pasted")})

Test that it works with Ctrl+C, Ctrl+V, Ok so far.

Now drag the image widget. The magic line appears and everything works fine.

Then edit the image and disable the "Captioned image" in the dialog.

Now when the image is dragged, the magic line doesn't appear and a paste event is fired upon drop, the HTML seems to include the whole widget.

Using the normal editor everything works fine, no paste is fired for dragging an image around.
