When a parent of a subsurface gets it state applied (either by a wl_surface.commit, wl_subsurface.set_desync or a recursive wl_surface.commit on a parent surface), the pending position state of the subsurface should be applied. If the subsurface is in effective synchronized mode (i.e. if its in explicit synchronized mode or any of its parent surfaces is a subsurface in explicit synchronized mode), the cached state should also be applied at this point, including its subsurface children, recursively. https://bugzilla.gnome.org/show_bug.cgi?id=743617
