Mapsui: Rotating a Forms map that contains a Pin crashes app

Adding a single pin using code from PinSample.cs, the pin shows up on the map as expected. Zooming and panning the map works fine. But about 75% of the time, rotating the map hangs the app with very little interesting debug output (debug build). The other 25% of the time the map rotates around the pin as expected. Map rotation always works without the pin. Same behavior on Android and iOS. I’m rotating the map using touch, not programatically.

Position p = new Position(41.0f, -116.0f);
var pin = new Pin(mapView)
{
  Label = $"PinType.Pin {markerNum++}",
  Address = p.ToString(),
  Position = p,
  Type = PinType.Pin,
  Color = new Color(rnd.Next(0, 255) / 255.0, rnd.Next(0, 255) / 255.0, rnd.Next(0, 255) / 255.0),
  Transparency = 0.3f,
  Scale = rnd.Next(50, 130) / 100f
};
mapView.Pins.Add(pin);
