Now that we keep the Wayland surface around for longer than the xwl_window, we might get events for that surface after the X11 window is unrealized.
Make sure we untag the Wayland surface when the Wayland surface is delayed, to break the wl_surface/xwl_window relationship, so that events for that surface are discarded by Xwayland.
