   6 <p> Test case for Bug <a href="https://bugs.webkit.org/show_bug.cgi?id=18655">18655</a>: [XHR] onProgress event
   7 needs to be dispatched according to what the specification states </p>
   8 <p> This test verify that we "dispatch a progress event called progress about
   9 every 50ms or for every byte received, whichever is least frequent".</p>
  10 <p> You should see a sequence of 5 PASSED. </p>
