2. Type a line of text.

3. Click on the RTL icon.

4. Select the line of text & click on the bulleted list icon.

Expected: A RTL bulleted list containing 1 list item is visible in the editor.

Actual: Nothing is displayed in the editor.

Scenario 2.

4. Click on Numbered List\Bulleted List or Decrease Indent icons.

Result: Nothing happens!!!

This is a regression in 3.5.3.

This defect is also reproducible on FF 3.6.6 so it is not only an IE bug.

Actually a dup of the (later) #7319 and #7320, fixed by #7294.
