2. Press 'Enter Key' to create a new paragraph;
3. Switch to 'Source' mode;
   • Expected Result:

     <p>
     	This is some <strong>sample text</strong>. You are using <a href="http://www.fckeditor.net/">CKEditor</a>.</p>
     <p>
     </p>
     
     

   • Actual Result:

     <p>
     	This is some <strong>sample text</strong>. You are using <a href="http://www.fckeditor.net/">CKEditor</a>.</p>
     <p>
     	&nbsp;</p>

This   is created by IE on empty paragraph when retrieving through innerHTML, and it's definitely eval coz it change the original document editing experience.

The patch is simply converting this:

<p>&nbsp;</p>

into

<p></p>

It's not a perfect solution because it has chance to conflict with user editing result, but seldom will user create a paragraph with such a pattern.

I've just had a talk with Garry. This is actually not a bug - the &nbsp; is needed to make the <p> block visible outside of the editor.
