Iron golems attack through the floor

As the title says Iron golems can attack through a slab floor 

Reproduce by making a slab floor roof over a room in a village and hurt a golem.

With the villager hitbox being so big and villagers inside the player golems should only aggro if you kill a villager not just axidentally (pun intended) when you are modifying the village.

getting randomly murdered by 5 golems because a villager ran into your tool is really irritating and is making the game difficult to play through random chance. especially when hitboxes are so sensitive.
