[Webkit] Enter works incorrectly into PRE blocks

[Karen Ananiev]

• Open editor and clear all content
  
• Apply Formatted paragraph format
  
• Type some chars and hit Shift+Enter or Enter
  

Outcome: cursor jumps to the start of the current line and new line is added before this one.

It seems that issue related with filling char (selection plugin) #1272

This got first broken in CKEditor 3.5.1 rev [6321]. When applying above TC you got the below:

<p>
	test test</p>
<p>
	test</p>
<pre>
</pre>
<p>
	&nbsp;</p>

After rev [6919] (CKE 3.6.1) the result changed to:

<pre>


</pre>
<pre>
test</pre>

The current result described in ticket has been reproducible from CKEditor 3.6.1 rev [6992] and looks like this:

<pre>

test</pre>

The one more use case:

1. Type any text and select it with ctrl-shift-left arrow
   
2. Apply any font name
   
3. Unselect text with right arrow key
   
4. Hit Enter and type text, select it with ctrl-shift-left arrow and apply another font name
   

Note that range is collapsed, cursor jumped to start of the paragraph and font name is not applied.

I noticed that setting new text to filling char node (fillingChar.setText()) collapses the range.

@karena your last comment refers to bug #8617 and not this one.

#9176, #8166, #10477 are two more ticket where this repository [6919] is mentioned.
