507308 - Cannot exit list when <li> contains <br>.

Status: UNCONFIRMED

(Core :: DOM: Editor, defect, P5)

Description

[Michael Thomas]

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.11) Gecko/2009060309 Ubuntu/8.04 (hardy) Firefox/3.0.11
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.1) Gecko/20090715 Firefox/3.5.1 (.NET CLR 3.5.30729)

For an <li> which does not contain a <br>, clicking the unordered list button will remove the list formatting for that line. For an <li> containing a <br>, the unordered list button creates a sublist inside the original <li>. This makes it impossible to exit the original <li> without going to the very end of the <li> and pressing enter.

This can be especially confusing if a user pastes a large amount of content into an <li>; they will have no way to break out of the list unless they go to the end.

Reproducible: Always

Steps to Reproduce:
1. Go to Midas Demo: http://www.mozilla.org/editor/midasdemo/
2. Enter the following HTML:
<ul><li>a<br>b</li></ul>
3. Place the cursor before the 'a'. Press the unordered list button.
Actual Results:  
Another ordered list is created inside the current <li>. Note that this is not the case if the <li> doesn't contain a <br>.

Expected Results:  
The contents of the <li> are moved out of the list. (any preceding list items remain in the list, any following list items are separated into a new list)
