[FF]: Problems with deleting last list item

[j.swiderski]

I have found this issue when reproducing 8248

Scenario 1

1. Paste the following code:

   <ol>
   	<li> FirstListItem  </li>
   	<li> SecondListItem
   			<ol> 
   				<li> ThirdListItem  </li>
   				<li>  FourthListItem  </li>
   				<li>  FifthListItem  </li>
   			</ol>
   	</li>
   	<li> SixthListItem  </li>
   </ol>
   

2. Place the cursor before "sixth item" ^SixthListItem and press backspace

Result: You wont be able to delete "3".
NOTE: Webkit and Opera concatenates fith item with sixth item - FifthListItemSixthListItem. IE puts sixth item in new paragraph. Not sure which behavior is correct.

---

Scenario 2

1. The same as above
2. Put the cursor behind fifth item FifthListItem^ and start pressing delete.

Result: When all text in sixth item gets deleted, number is deleted at the end.

Normalize this specific backspace to MS-Word alike behavior which outdent the list item.

The idea is good and it works well.

But just to avoid people complaining later, let's have it working well for this case:

1. Load this HTML and selection:

   <ul>
   	<li>
   		<p>Para 1</p>
   		<p>^Para 2</p>
   	</li>
   </ul>
   

2. BACKSPACE

After patch, the li will outdent, instead of having the paragraphs merged.
