HeatMapLayer: Options: drawOrder property?

[MichaelBakkerDP]

The documentation for the HeatMapLayer Options object defines a 'drawOrder' property, with which a z-index like value can be set to control layering. See documentation.
However the typescript definition (loaded through:
https://www.bing.com/api/maps/mapcontrol?callback=initBingMap&key=${ key }
) does not expose this field.
This may be the case, but what is the alternative for this field? I.e. how can i control the order or depth in which this layer is drawn?

The documentation is correct, and HeatMapLayer will respect the drawOrder property. The type declaration is in error here.
