I see the red box for the eyes not the same from the top of the players hitbox, either if he is sneaking or not.

It can be an issue for map makers trying to detect if a player touchs a block above him.

eg:
_{execute as @a[...] at @s anchored eyes if block ~ ~0.19 ~ red_concrete run kill @s}

shouldn't it be logical to have the eyes position the same from the top of the hitbox?
