In the Map Viewer when a layer is set with a feature display order, and it uses vector polygons (hatch fill in this case) the features are not displayed in order and hatch fill polygons are generally displayed over solid fill polygons. There are other drawing errors as well.

Does anyone have a work around for this? Is this a bug? Can you re-produce?
