           Summary: querySelectorAll('body>:last-child') does not work
                    unless HTML file ends with 'new-line'.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: hayato at chromium.org

test1.html

Please see attachment files, test1.html and test2.html. The only difference between them is whether there is a 'new-line' at the end of file or not.

- test1.html ends with 'new-line', like '... </html>\n<EOF>'
- test2.html does not end with 'new-line', like '.... </html><EOF>'.

Open each files, then try the following JavaScript code in JavaScript console.

 > document.querySelectorAll('body>:last-child')

The results differs in test1.html and test2.html:
  - In test1.html, querySelectorAll returns a correct result, ['<div id="last">last</div>].
  - In test2.html, querySelectorAll returns an empty list, [], which is wrong result.

This might be a regression because Safari Version 5.0 (6533.16) returns the same correct results for both test1.html and test2.html.
