[IE] Pasting over a readonly block merge the siblings and the pasted content

[Saare]

• Load the following HTML:

  <p>
  	Para 1</p>
  <p contenteditable="false">
  	Para 2</p>
  <p>
  	Para 3</p>
  

• Right click "Para 2".
• Paste some content.

Notice that para 1, the pasted content and para 3 are merged into one paragraph.

In my opinion if contenteditable="false" is set, only Copy should be allowed, or everything should be blocked.

Replying to krst:

In my opinion if contenteditable="false" is set, only Copy should be allowed, or everything should be blocked.

That's true if you're inside read-only content, but not if you select the entire read-only element as a whole, which is what I think is happening in this tc.

A read-only element works much like an image, so it can be entirely deleted/replaced if the selection fully includes it, outside its boundaries.

Note that the following represents the selection in IE, when right clicking with the above tc:

<p>
	Para 1[</p>
<p contenteditable="false">
	Para 2</p>]
<p>
	Para 3</p>

So, theoretically, joining paragraphs is correct... but of course, this is not the way users see it.
