Charge attack can be used on a dying ender dragon, consuming durability on the spear

A dying ender dragon can be hit by a spear’s charge attack, consuming durability on the spear if the wielder is in survival or adventure mode.

This does not happen with other dying mobs. Dying ender dragons cannot be hit by regular melee attacks (but, like other dying mobs, they still prevent the hit from connecting with whatever is behind their hitboxes).

To reproduce

1. Grab a spear, elytra and some firework rockets

2. Go to near 0, 0 (most likely you’ll want to do this in the end)

3. If you wish to test in survival mode, /effect give @s minecraft:resistance infinite 4 true

4. /summon ender_dragon ~ ~ ~ {DragonPhase:9}

5. While the dragon is dying, fly into it while using the charge attack
   ❌ Your charge attack hits the sub-hitboxes of the dying dragon and your spear loses durability

Expected result

The spear would not connect on the dying ender dragon and no durability would be lost.
