The behaviour we check for to see if a unit is currently the target of a Graviton Beam is ONLY applied by the periodic effect set of the Graviton ability, NOT in the initial effect set. This means there can be a slight delay between when the Graviton is cast and when the target unit is considered a Graviton target by other abilities.
Creates unintended scenarios. For instance, a Phoenix can cast Graviton Beam on a widow mine only for the Terran to issue an order to pick up the mine with a medivac after Graviton has already been cast, which causes the Phoenix to lose energy for no effect and the mine to be picked up since it is incorrectly considered a valid target.
