[Webkit] adds inline styles on drag and drop operation

[Karen Ananiev]

• Edit contents.css
  
• Add any CSS rule. For example, h1 { color:red }
  
• Open editor and create H1 element with some text
  
• Select the text of this header element and drag and drop it on other place
  
• Switch to source mode
  

You'll get something like

<h1 style="color: red; ">
	header 1</h1>

I have used replacebycode sample (with two editors) to reproduce the issue.

Result of dragging header from one editor to another is as follows:

<div style="font-family: Arial, Verdana, sans-serif; font-size: 12px; color: rgb(34, 34, 34); background-color: rgb(255, 255, 255); ">
	<h1 style="color: red; ">
		text</h1>
</div>

Issue is reproducible on Webkit browsers from CKE 3.0

#7146 is probably related to this one.

@fredck comment from #6121:

WebKit is well known about changing dragged or pasted stuff. We're not able to fix it. All we can do is reporting it to them, so they can make things work properly at their side.

Whether it's dragging or pasting the cause and result is the same.

I'm closing this issue as a DUP of #7146 as the later has more information.
