Forms iOS Zoom/Pan Map Hang

Using the Xamarin.Forms "Change Basemap" sample from the Runtime GitHub. Simply added the enable location code to the Initialize method:

private void Initialize()
// Create new Map with basemap
Map myMap = new Map(Basemap.CreateTopographic());

// Assign the map to the MapView
MyMapView.Map = myMap;

// Wait for the MapView to load.
MyMapView.PropertyChanged += (o, e) =>
if (e.PropertyName == nameof(MyMapView.LocationDisplay) && MyMapView.LocationDisplay != null)
MyMapView.LocationDisplay.IsEnabled = true;

Debug the sample (using VisualStudio 2019 16.3.5), Do a bunch of zooming in and out and after a couple seconds, the app just hangs. I first saw it in my own app and decided to try and repro it with a sample. It seems to repro every time for me.

I think this may be the same issue as some random hanging in my production app that i'm getting reports of, but I can't reproduce it solidly in production.

Hope you can help. Thanks.
