Over zoom beyond maximum zoom level doesn't work in MapView

According documentation it is possible to allow user to over zoom beyond maximum zoom level by defining maxScale constraint on MapView to 0.

const mapView = new MapView({
      container: "containerDiv",
      map: map
});
mapView.when(lang.hitch(this, function(event){
      mapView.constraints.maxScale = 0;
}));

But it doesn't work, MapView is always locked at basemap's maximum zoom level.

If I set zoom levels on the view by adding extra levels it works.

mapView.when(lang.hitch(this, function(event){
      mapView.constraints.lods = [
         // basemap's maximum zoom level
         // extra zoom level
      ];
}));

Has anyone ever implemented this behavior ?
