Scene Transition with Brightness and Temperature Change

I am attempting to activate a scene on an IKEA Zigbee light (via ZHA) through an automation:

service: scene.turn_on
  entity_id: scene.office_night
  transition: 300

The scene involves changing both the brightness and color temperature. With no transition, this change occurs properly, but when setting a transition time, only one of the attributes (color temperature or brightness) change. I can set the scene again after this action to ensure the light ends in the proper state, but it mostly defeats the purpose of the transition.
Does this seem like an issue with HA, ZHA, or the light? This is the only light I currently own which allows changing color temperature, so I have nothing to compare to.
