At least one WM (KDE's KWin) does not generate X11 configure events when dragging
a window using gtk_window_begin_move_drag(). We need the configure events so we
can generate wxMoveEvent, which AUI needs in order to re-attach a floating pane.
This is functionally a revert of b8789b9d6f for backends other than Wayland.
