This bug was fixed in the package gnome-shell - 41.3-1ubuntu1

    This can be handled fully by the extensions that need it, so let's
    handle this in dash-to-dock instead that in upstream code
  * Remaining changes with debian:
    - Replace gnome-backgrounds dep with ubuntu-wallpapers and Suggests
      gnome-themes-standard-data, gnome-backgrounds

        stable.
    - ubuntu/smarter_alt_tab.patch:
      + quick alt-tab (without showing up the switcher) switch only between
        the last window of the last 2 applications to be focused instead of
        raising all windows of those apps.

      + Allow user switching when using LightDM.
