After review by the development team, it has been determined that this issue is related to a known limitation with the software that lies outside of Esri's control. The issue's Additional Information section may contain further explanation.
The labelOptions parameter must be set in featureLayer.LabelingInfo structure. The server already provides labeling options but users may change them.
