... and Emacs only fills its text into the areas provided and exposed by
the window manager.  As a rule, never trust the order of execution in
such case.  Resizing child frames is already tricky enough with GTK3 and
some window managers.  We have the variable 'x-gtk-resize-child-frames'
for that but setting it shouldn't change anything in the case at hand.
Neither should 'x-gtk-use-window-move' help but you can still try.
