Incorrect/Imprecise Placement of Armor Stands with "Small" entity data

Placing an armor stand against a wall causes its head to be placed at the mouse cursor rather than its feet. This works fine for regular 2-block armor stands, but when placing an armor stand with {Small:1b} set in the item's entity_data (EntityTag prior to 24w09a), it causes the entire armor stand to be shifted down a full block from the cursor's position.

Potentially related to MC-123453 (and now MC-195002) as this started happening at around the same time it was fixed.

Steps to reproduce:

• Run

  /give @s armor_stand[minecraft:entity_data={id:"minecraft:armor_stand",Small:1b}]

• Place it on a wall several blocks off the ground.

• Watch in amazement as it appears nowhere near your crosshairs.
