      7 * It's possible for us to restore windows without tabs,
      8 * when on Windows/Linux the user closes the last tab as
      9 * a means of closing the last window. That last tab
     10 * would appear as a closed tab in session state for the
     11 * window, with no open tabs (so the state would be resumed
     12 * as showing the homepage). See bug 490136 for context.
     13 * This test checks that in this case, the resulting window
     14 * is functional and indeed has the required previously
     15 * closed tabs available.
