If I use the mouse to move or zoom the map, the next map.set_position centers intermittently in random places

Hi, I'm having a problem with a moving map for aircraft. If I just let it run it works great, but if I move the map display with the mouse or change the zoom with the mouse, the next time this code is run, it intermittently centers in Brazil. Once that happens, it never centers in the correct place again. Can you help?

This code runs on a timer:

            self.map_widget.set_position(self.address_lat, self.address_lon)
            if self.auto_zoom_flag.get() == True:
                # Set zoom level based on aircraft speed 1 is zoomed all the way out, 
                # 19 all the way in
                zoom_level = 19-int(flight_position_data[0].get("speed")/600*19)
                if zoom_level <= 3:
                    zoom_level = 3
                elif zoom_level >= 14: zoom_level = 14
                self.map_widget.set_zoom(zoom_level)
            self.airplaneMarker.set_position(self.aircraft_lat, self.aircraft_lon)

Start with the timer callback shown in the issue and trace the interaction between map_widget.set_position, map_widget.set_zoom, and mouse panning or zooming. Reproduce the problem by moving or zooming the map before the next callback, then verify that repeated updates continue centering on the requested aircraft coordinates rather than an unrelated location.
