GtkOverlay above a GtkClutterEmbed broken on Wayland

Submitted by Jonas Ådahl Link to original bug (#772225)
Description
GtkClutterEmbed uses a subsurface that is positioned above main window surface. When placing a GtkOverlay above the GtkClutterEmbed widget, nothing of the GtkOverlay shows up.
For it to work, the GtkOverlay window content should be placed in its own subsurface that should be placed above the GtkClutterEmbed widget's subsurface.
