Pillagers and piglins can hardly hit the mobs lower than a block with a crossbow

The bug

Pillagers and piglins can hardly hit the mobs lower than a block with a crossbow.
Unlike MC-260003, the pillagers and piglins will try to aim downward, but the angle of aiming downward is still not enough.

Reproduce steps

1. Give yourself a pillager spawn egg.
2. Give yourself a piglin spawn egg.

   /give @p piglin_spawn_egg[entity_data={id:piglin,IsImmuneToZombification:1,IsBaby:0,equipment:{mainhand:{id:'minecraft:crossbow'}}}] 1

3. Give yourself a baby turtal spawn egg.

   /give @p turtle_spawn_egg[entity_data={id:turtle,Age:-999999}] 1

4. Spawning a pillager or piglin.
5. Spawning a baby turtle on the third block from the pillager or piglin.
6. Use the following command:
   Pillager

   /damage @e[type=minecraft:pillager,limit=1] 1 minecraft:generic by @e[type=minecraft:turtle,limit=1] from @e[type=minecraft:turtle,limit=1]

   Piglin

   /damage @e[type=minecraft:piglin,limit=1] 1 minecraft:generic by @e[type=minecraft:turtle,limit=1] from @e[type=minecraft:turtle,limit=1]

7. Found out that the pillager or piglin is difficult to hit the target.
