I'm plotting a set of Coordinates for a hiking trail, and in instances where the trail is an Out & Back and has duplicate Coordinates:

Code Block return new mapkit.Coordinate(point[0], point[1]);

...what ends up happening is that the coordinate disappears altogether from the map.

I'm plotting them with a pretty simple PolylineOverlay:

Code Block const trail = new mapkit.PolylineOverlay(coords, { style });

...with the following style:

Code Block const style = new mapkit.Style({
    strokeColor: colors.purple,
    lineWidth: 2,
    lineJoin: 'round',
    lineDash: [],
});

This works fine when I plot duplicate coordinates on iOS. How do I get this working with Mapkit JS?
