1. Load the following HTML:

<p>Para 1</p>
<p contenteditable="false">Non Editable</p>
<p>Para 2</p>

2. Hit CTRL+A to select all.

3. Hi the list button.

Current results:

<ul>
	<li>
		Para 2</li>
	<li>
		Para 1</li>
</ul>
<p contenteditable="false">
	Non Editable</p>

Expected results:

	<li>
		Para 1</li>
</ul>
<p contenteditable="false">

<ul>
	<li>
		Para 2</li>
