BIDI: Mixed LRT/RLT direction causes incorrect behaviour

[Paweł Horzela]

Paste source:

<ul dir="rtl">
	<li dir="ltr">
		item 1</li>
	<li>
		item 2</li>
</ul>

Incorrect behaviours:

1. First item ('item 1') bullet icon is not visible in Opera, FF and Chrome.
   
2. When you set focus on first item ('item 1') and decrease indent, it becomes RTL instead of remain as LTR.

[Krzysztof Studnik]

Confirmed since CKE 3.0

[Garry Yao]

@Krst, "version" should only be used with absolute confidence.

1. A browser bug, just like #6249;
2. Caused by [5857], not a recent regression.

[Tobiasz Cudnik]

Patch fixes the preservation of the direction on an outdented list item to a paragraph.

Fixed with [6255].
