Unexpected behavior when toggling bulleted/numbered list with a floating element

[Pablo Vanwoerkom]

Enter the following in the ckeditor.

<p>
	paragraph 1 with float left image <img src="http://a.cksource.com/c/1/inc/img/logo-ckfinder.gif" style="float: left;" /></p>
<p>
	paragraph 2</p>
<p>
	paragraph 3</p>

Select all text and then hit the bulleted/numbered list button. This will move the image into it's own bullet, separated from paragraph 1. If you click on a list button again, the image is now in it's own paragraph. If you click it again, the image will disappear and its atrributes will get moved to the <li> tag and the bullet will just contain a &nbsp;.

This was tested in Firefox 3.5.
