When adjusting the camera position, the listener callback never gets invoked providing the reason.

All animateCamera, moveCamera and jumpCamera invocations call into the camera dispatcher as:

cameraChangeDispatcher.onCameraMoveStarted(
OnCameraMoveStartedListener.REASON_API_ANIMATION);

The reason is provided, please clarify what you mean with adjusting the camera position?

I'm going ahead and will look into this in function of #9320.
