  70 This test:
  71 -Builds up a list of state object entries with fragment URLs.
  72 -Navigates through them to verify that the popstate event is fired.
  73 -Navigates away to a new document, with the old document being destroyed.
  74 -Navigates back to the state object entries and verifies the pageshow or popstate events are fired on the new documents.
