   6 <p> Test case for <a href="https://bugs.webkit.org/show_bug.cgi?id=36156"> bug 36156</a>: XHR 'progress' event code assumes wrongly that expectedLength >= 0</p>
   7 <p> Verify that the progress event total property is 0 when the expected overall length can't be computed.<p>
   8 <p>PASS should appear below:</p>
