485466 - execCommand("outdent") unexpectedly removes <li> when <ul> is a child of it

Status: NEW

(Core :: DOM: Editor, defect, P3)

Description

[Annie Sullivan]

Steps to reproduce:
1. Go to Midas Demo: http://www.mozilla.org/editor/midasdemo/
2. Enter the following HTML:
<ul><li>a<ul><li>b</li></ul></li></ul>
3a. Place cursor after "b". Press Outdent button. Result: List item is removed instead of outdenting (HTML: <ul><li>a<br>b</li></ul>)
3b. After step 2, place cursor after "a". Press Outdent button. Result: Nothing happens.

Expected result: this should work the same as if the HTML were "<ul><li>a</li><ul><li>b</li></ul></ul>" (ul child of ul).

The behavior has changed, it now generates <ul><ul><li>a<br>b</li></ul></ul>.
