Build ID: 20110928134238

Steps to reproduce:

When multiple DIVs with contenteditable="true" attribute located inside another DIV, document.execCommand('justifyleft',null,null) (same for justifyright and justifycenter) throws an exception for the first div in the group.

Example code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:v="urn:schemas-microsoft-com:vml">
  <head></head>
  <body>
    <div> 
        <div style="border:1px dashed black;width:400px;height:50px;" contenteditable="true">
        Doesn't work
        </div>
        <div style="border:1px dashed black;width:400px;height:50px;" contenteditable="true">
        Works properly
        </div>
        <div style="border:1px dashed black;width:400px;height:50px;" contenteditable="true">
        Works properly
        </div>
    </div>
    <br/><br/>
    <input type="button" onclick="document.execCommand('justifyleft',null,null);" value="Left" />
    <input type="button" onclick="document.execCommand('justifycenter',null,null);" value="Center" />
    <input type="button" onclick="document.execCommand('justifyright',null,null);" value="Right" />
  </body>
</html> 

Selecting text in the second or third div and clicking one of the buttons works as expected.
Selecting text in the first div and clicking one of the buttons results in:

Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMHTMLDocument.execCommand]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame :: file:///C:/Users/dev/Desktop/test.html :: onclick :: line 1"  data: no]
