  87 This test:
  88 -Builds up a list of state object entries with fragment URLs.
  89 -Navigates through them to verify that the popstate and hashchanged events are fired.
  90 -Navigates away to a new document, with the old document being destroyed.
  91 -Navigates back to the state object entries and verifies the pageshow or popstate events are fired on the new documents.
