Bug#941123: Acknowledgement (gdm3: action-middle-click-titlebar 'lower' is ignored: can't set window to lower on title bar middle-click)

[Conrad Hughes]

Urgh, too late I manage to crack Gnome's search engine.  This seems to
appear upstream in a few contexts, but I don't understand what the
consequences are for a fix in Debian:

  https://gitlab.gnome.org/GNOME/gnome-shell/issues/773
  Closed; says it's applications' fault!

  https://gitlab.gnome.org/GNOME/mutter/issues/602
  .. points to
  https://gitlab.gnome.org/GNOME/gtk/issues/539
  .. where the same guy says it's applications' fault.

  https://gitlab.gnome.org/GNOME/gtk/issues/1895
  .. where it looks as if the 'lower window' implementation has
  never been completed.
