New paragrahps added when saving bullet list with indented items

[Titus]

Running CKEDITOR in Wordpress, when I save a text with an existing bullet list that has indented items such as the below, the article gets returned (after saving) with an additional line with P marks, right before the indented bullet. The more often I save, the more paragraphs are created.

<ul>
	<li>&nbsp;</li>
	<li>adalksdjaskldjasld alksdj asldkajd lak</li>
	<li>adalksdjaskldjasld alksdj asldkajd lak
	<ul>
		<li>adalksdjaskldjasld alksdj asldkajd lak</li>
		<li>adalksdjaskldjasld alksdj asldkajd lak</li>
	</ul>
	</li>
	<li>adalksdjaskldjasld alksdj asldkajd lak</li>
	<li>adalksdjaskldjasld alksdj asldkajd lak</li>
	<li>&nbsp;</li>
</ul>

I cannot reproduce this on clean CKEditor. Can you do it on ​http://ckeditor.com/demo? I was checking by switching between modes, what simulates saving and loading data.

Editor itself doesn't have anything with data saving so this is most likely something on Wordpress side.
I have tried reproducing this issue on plain AJAX sample where getData is called (can be used to put data into request or write data somewhere else) and there was nothing wrong.

I'm closing this issue as invalid.
