Disappearing paragraph after lists (IE Only)

[Josh]

I previously mentioned this on ticket #7364 but that was closed for a more recent duplicate. Since the new ticket does not specifically mention this problem, I'm making it its own ticket.

Paste into source view:

	<ul>
	<li>item 1</li>
	<li>item 2</li>
	</ul>
	<p>paragraph</p>

In editing view, place your cursor in front of the word "paragraph" and hit backspace once. Return to source view and you will see it has created the following invalid html:

	<ul>
	<li>item 1</li>
	<li>item 2</li>
	paragraph</ul>

Worse, when the editor tries to work with the invalid html it will "correct" its mistake. To see this, now change the list formatting (for instance from unordered to ordered list) and it will delete the paragraph entirely. You can try this demo with a large paragraph instead of just the word "paragraph", and you will see the whole paragraph disappear from the document.

I have been able to reproduce it only in IE8 for Win XP.

NOTE: This is not a dup of #6173. The applied patch doesn't solve this issue but also produces extra error.

I can no longer reproduce this issue in CKEditor 4.x.
