Oops, making changes in PosePickerSupport would sometimes trigger a re-fetch in PosePicker.
Specifically, PosePicker needs some fields that PosePickerSupport doesn't, so changing the canonical poses causes PosePicker to ask for stuff again—which will probably serve a SWR'd cached version that doesn't reflect the Support changes!
Here, we update the PosePickerSupport query to prefetch all the fields the PosePicker _would_ want for any of these poses. That way, if we swap in a new one as the canonical appearance for a pose, there's no refetch needed, and therefore no risk of hitting a stale cache.
