android - not - MarkerClick funciona pero InfoWindowClick no abre ViewModel

xamarin forms maps xaml

Question

La siguiente implementación de MarkerClick funciona perfectamente bien. Pude abrir otra vista a través de ShowViewModel

View.cs

mMap.MarkerClick += MMap_MarkerClick;
private void MMap_MarkerClick(object sender, GoogleMap.MarkerClickEventArgs e)
{
ViewModel.MapInfoSelected(e.Marker.Title);
}

ViewModel.cs

public void MapInfoSelected(string name)
{
ShowViewModel<StudentViewModel>(new { studentName = name});
}

InfoWindowClick no se InfoWindowClick para abrir otra Vista.

View.cs

mMap.InfoWindowClick += MMap_InfoWindowClick;
private void MMap_InfoWindowClick(object sender, GoogleMap.InfoWindowClickEventArgs e)
{
ViewModel.MapInfoSelected(e.Marker.Title);
}

ViewModel.cs

public void MapInfoSelected(string name)
{
// it hits here, but does not hit `StudentViewModel` Init() method, the app is frozen and do nothing
ShowViewModel<StudentViewModel>(new { studentName = name});
}

Incluso probé SetOnInfoWindowClickListener siguiente manera, tampoco abre la Vista.

 mMap.SetOnInfoWindowClickListener(this);
public void OnInfoWindowClick(Marker marker)
{
ViewModel.MapInfoSelected(marker.Title);
}

ACTUALIZAR:

Incluso golpea el método OnPause() , pero aún no llama al StudentViewModel Init () de InfoWindowClick si uso el evento InfoWindowClick

 public override void OnPause()
{
base.OnPause();
mMap.InfoWindowClick -= MMap_InfoWindowClick;
}
