      2 <p>Test that a 404 response for manifest results in cache removal.</p>
      3 <body>
      4 <ul>
      5 <li>Frame 1: Manifest is still available, so a new master resource is added to the cache.
      6 <li>Frame 2: Manifest loading results in 404 response, so the cache group becomes obsolete, and an obsolete event is dispatched (because the document in frame was associated with a cache in the group).
      7 <li>Frame 3: Manifest is still 404 - the document is never associated with a cache.
      8 <li>Frame 4: Manifest is now available, so the document gets associated with a cache in a newly created group; the obsolete cache group is not affected.
      9 </ul>
     10 <p>Should say SUCCESS:</p>
