@Override

    // Home loads the content of the workspace on a background thread. This
    // means that
    // a previously focused view will be, after orientation change, added to
    // the view
    // hierarchy at an undeterminate time in the future. If we were to
    // invoke
    // super.onRestoreInstanceState() here, the focus restoration would fail
    // because the
    // view to focus does not exist yet.
    //
    // However, not invoking super.onRestoreInstanceState() is equally bad.
    // In such a case,
    // panels would not be restored properly. For instance, if the menu is
    // open then the
    // user changes the orientation, the menu would not be opened in the new
    // orientation.
    //
    // To solve both issues Home messes up with the internal state of the
    // bundle to remove
    // the properties it does not want to see restored at this moment. After
    // invoking
    // super.onRestoreInstanceState(), it removes the panels state.
    //
    // Later, when the workspace is done loading, Home calls
    // super.onRestoreInstanceState()
    // again to restore focus and other view properties. It will not,
    // however, restore
    // the panels since at this point the panels' state has been removed
    // from the bundle.
    //
    // This is a bad example, do not do this.
    //
    // If you are curious on how this code was put together, take a look at
    // the following
    // in Android's source code:
    // - Activity.onRestoreInstanceState()
    // - PhoneWindow.restoreHierarchyState()
    // - PhoneWindow.DecorView.onAttachedToWindow()
    //
    // The source code of these various methods shows what states should be
    // kept to
    // achieve what we want here.
