Fixed

• Closing the viewer, then pressing back, opened the file again with the
  Files app on vue-router 5. Its navigations land asynchronously, and the
  viewer tagged the history entry before the router had created it, so it
  found nothing to unwind on close. History changes now wait for the
  router's navigation (#74)
