[IE10] Double enter doesn't escape from list

[Artur Delura]

I have written manual test for that:

test.html

<textarea cols="80" id="classic" name="classic" rows="10">
&lt;ol&gt; &lt;li&gt;&lt;strong&gt;Command Module&lt;/strong&gt; with a cabin for the three astronauts which was the only part which landed back on Earth&lt;/li&gt; &lt;li&gt;&lt;strong&gt;Service Module&lt;/strong&gt; which supported the Command Module with propulsion, electrical power, oxygen and water&lt;/li&gt; &lt;li&gt;&lt;strong&gt;Lunar Module&lt;/strong&gt; for landing on the Moon.&lt;/li&gt; &lt;/ol&gt;
</textarea>
<script>
	var editors = CKEDITOR.replace( 'classic' );
</script>

test.md

@bender-ui: collapsed
@bender-tags: 4.5.0, tc
@bender-ckeditor-plugins: wysiwygarea, toolbar,basicstyles, list, indentlist

* Put a caret at the last item of the list.
* Double enter to escape the list.

**Actual result: ** New list items are created.
