MapView overlays blocking zooming

In my current project I’m updating my app from ArcGIS runtime 10.2 to 100.7. In 10.2 we add UI elements to the collection of overlays and have no issues zooming, but in 100.7 whenever I add a UI element to the collection of overlays there is a dead zone wherever the control is. Is there a way to work around this?

Below is the code to replicate the issue, I’ve tried the same code using the 10.2 ArcGIS Nuget package and the zooming works

MainWindow.xaml

            <esri:ArcGISTiledLayer x:Name="Basemap"

        </esri:Map>
    </esri:MapView>
    <Button Content="Create Rectangle"
            Click="OnButtonClick"
            Grid.Column="0"
            Grid.Row="0"/>
</Grid>

MainWindow.xaml.cs

private void OnButtonClick(object sender, RoutedEventArgs e)
{
    Random rng = new Random();
    MapPoint point = new MapPoint(rng.Next(1, 100), rng.Next(1, 100), SpatialReferences.Wgs84);
    var rect = new BigRectangle();
    GeoView.SetViewOverlayAnchor(rect, point);
    MyMapView.Overlays.Items.Add(rect);
}

BigRectangle.xaml

<UserControl x:Class="EsriTestApp.BigRectangle"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         xmlns:local="clr-namespace:EsriTestApp"
         mc:Ignorable="d" 
         d:DesignHeight="450" d:DesignWidth="800">
<Grid>
        <Rectangle Width="100"
                   Height="50"
                   Fill="FloralWhite"
                   Stroke="Black"/>
</Grid>

I’m not quite sure what to do here. I’ve tried a few different things like attempting to reroute the MouseWheel event on the BigRectangle.cs class the MapView.MouseWheel event but all of the code to send events to that event’s handler seems to be internal (MapView.OnMouseWheel() etc). The only way I’ve been able to get around this is to create an event handler for the MouseWheel event on BigRectangle.cs and call the MapView SetViewpointScale method to zoom the map, but I can’t quite figure out the scale I need to accomplish this.

rect.IsHitTestVisible = false;
