Simple HTML file with basic test case.

In some cases, using "InsertUnorderedList" or "InsertOrderedList" command on editable + designMode content allows to insert bullets to elements, but not to remove them.

Steps to reproduce
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
1) Click in a DIV having properties: contentEditable=='true' and designMode == 'on'
2) Paste the following text in the DIV:

This is my list of items:
Item 1
Item 2
Item 3
This is the end of my list.

3) Select the lines "Item 1" to "Item 3"
4) Execute the following command in the debugging console: "{myEditableDiv}.execCommand("InsertUnorderedList", false, null)"
- (List is now bulleted)
5) Execute the same command in the debugging console, again: "{myEditableDiv}.execCommand("InsertUnorderedList", false, null)"

Actual result
¯¯¯¯¯¯¯¯¯¯¯¯¯
- List is still bulleted

Expected result
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
- List is unbulleted

Additional notes
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
- Works fine with single line selected
- If multiple lines are selected, if words fine if and only if the last line is part of the selection

- Reproduced under Google Chrome 18.0.1025.162 release, Google Chrome 20.0.1113.0 canary and Safari 5.1.2
