How to use DataGrid with DataGridCollectionView as ItemsSource and still use CompiledBindings?

[sn4k3]

I've a DataGrid with groups which I set ItemSource to a instance of DataGridCollectionView:

public ObservableDictionary<string, NameValueGroup> TabularData { get; } = new();
// ....
TabularDataGroupView = new DataGridCollectionView(TabularData);
TabularDataGroupView.GroupDescriptions.Add(new DataGridPathGroupDescription($"Value.{nameof(NameValueGroup.Group)}"));

However, I'm not able to use CompiledBindings anymore since the type is now DataGridCollectionView instead of ObservableDictionary<string, NameValueGroup>. Using ReflectionBinding works... How can I enforce the bindings type to the correct type?
