When tracking, RA/Dec should remain constant, while Alt/Az change (following the object across the sky).
When parked, Alt/Az (and also Dec :) ) should remain constant, while RA changes -- I would want to see what hour angle the parked scope is currently pointed at; this is great information for telemetry from a remote observatory.

Kstars correctly shows the "stars sliding by" with the mount staying at the parked position.
Ekos is not updating (only in SCOPE_PARKED state).
