The output of Operator: Entity Position returns the position of every entities foot block except for players.
This makes for no possible easy way to provide consistent effects for both mobs and players.

In my opinion a separate Selector: Entity Eye Position in addition to Selector: Entity Position that return the eye and foot positions respectively could be a good solution.
