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