Webkit: Dragging image wrapped in block element leaves empty block elements in content area.

[Jakub Ś]

1. Go to ​http://ckeditor.com/demo
2. Drag image in few places inside content area
3. Switch to source and notice that there are many empty headers inside content area <h1>&nbsp;</h1>

I have also tried using the below code (img inside div)

<div>
	<img alt="" src="http://a.cksource.com/c/1/inc/img/demo-little-red.jpg" style="margin-left: 10px; margin-right: 10px; float: left; width: 120px; height: 168px;" /></div>
<h1>Little Red Riding Hood</h1>

Unlike in Firefox (#8883) here div is lost on first drag. Wrapping div stays at the top. Never the less dragged image splits paragraphs in two(despite not having any surrounding div).

Issue reproducible in Webkit from CKEditor 3.0
