/**
* Checks that restoring the last browser window in session is actually

* 1.1) Open a new browser window
* 1.2) Add some tabs
* 1.3) Close that window
* 1.4) Opening another window
* --> State is restored
*
* 2.1) Open a new browser window
* 2.2) Add some tabs
* 2.3) Enter private browsing mode
* 2.4) Close the window while still in private browsing mode
* 2.5) Opening a new window
* --> State is not restored, because private browsing mode is still active
* 2.6) Leaving private browsing mode
* 2.7) Open another window
* --> State (that was before entering PBM) is restored
*
* 3.1) Open a new browser window
* 3.2) Add some tabs
* 3.4) Open some popups
* 3.5) Add another tab to one popup (so that it gets stored) and close it again
* 3.5) Close the browser window
* 3.6) Open another browser window
* --> State of the closed browser window, but not of the popup, is restored
*
* 4.1) Open a popup
* 4.2) Add another tab to the popup (so that it gets stored) and close it again
* 4.3) Open a window
* --> Nothing at all should be restored
*
* 5.1) Open two browser windows and close them again
* 5.2) undoCloseWindow() one
* 5.3) Open another browser window
* --> Nothing at all should be restored

* Checks the new notifications are correctly posted and processed, that is
