BIDI: Increase RTL list item indent doesn't work.

[paho]

1. Paste source into IE:

   <ul>
   	<li dir="rtl">
   		List item</li>
   </ul>
   

2. Set focus on 'List item' element and increase indent.

Result: Indent is not increased, but when you go to source view you can notice that 'margin-left' of <ul> element is increased.

Above source is generated only in IE. In other browsers generated source looks like:

<ul dir="rtl">
	<li>
		asdasd</li>
</ul>

and it works fine.

To generate source in IE:

1. Click on 'New Page' on toolbar.
   
2. Click on bullet list icon and type some text.
   
3. Press 'Enter' and click on bullet icon to remove list in second line.
   
4. Press Ctrl+A and then RTL icon.

This defect can also be seen in FF 3.6 using the following source:

<ul>
	<li>
		List item 1 (LTR)</li>
	<li dir="rtl">
		List item 2 (RTL)</li>
	<li>
		List item 3 (LTR)</li>
</ul>

Highlight the 2nd list item and click on Increase Indent. The same result as above can be observed.

The ticket itself is a DUP of #6569, while for the case reported by James, it's a different bug (transform a list instead for indenting a list) so we should open new ticket for it.
