Sharpness enchantment on thrown trident doesn't work for ender dragon or other mobs with mutiple hitboxes(entities that has green hitbox when use f3+b is on).

Steps to Reproduce:

1. Run command:

   /give @s trident{Enchantments:[{id:sharpness,lvl:255},{id:loyalty,lvl:5}]}
   

1. Go to the end and throw the trident to the ender dragon. It will only take a little damage, the damage from thrown trident itself.
2. But if you attack ender dragon directly, it will take much damage.
3. This bug may occur on other mutliple-hitbox entities if mods is installed.
4. Other enchantments which can increase damage such as smite and impaling may also have this bug.

What I expected to happen was...:
Enchantment sharpness can deal damage to multiple-hitbox entities on thrown trident, like one-hitbox entities(sharpness on thrown trident can deal damage to normal entities).
