I need to ensure that the symbology is always oriented upwards - i.e. not rotated with the dataframe.
I've updated the following registry key, and this helps ensure that when viewed in the MXD, and created as PDF output, the icons are oriented correctly, i.e. towards top of page/screen.
However, in my web client, when my app does a MapServer export with rotation, the symbology is always oriented North - e.g.:

Is there something I can do to ensure that the icons are not rotated?
Note - this is also asked at https://geonet.esri.com/message/687825-prevent-rotation-of-symbols-in-map-service-export-request
