Ghast fireballs either do not destroy end crystals or delete them without detonating them

Summary

When a ghast fireball either impacts an end crystal directly or explodes very nearby, the crystal either remains completely unaffected or is deleted without detonating, depending on the fireball’s impact/explosion location relative to the crystal. (/gamerule mob_griefing has no effect whatsoever.)

Steps to Reproduce

1. Enter a world running any version from 1.21 up to 26.3 Snapshot 9.

2. Place an end crystal on a block of obsidian or bedrock.

3. /summon minecraft:armor_stand ~ ~ ~ {NoGravity:1b,Passengers:[{id:ghast}]}

4. Switch to survival mode and stand directly inside or behind the End Crystal's hitbox.

5. Observe the enemy projectiles hitting the crystal. [1]

Observed Results

The fireballs impact the crystal but deal zero damage to it, or they delete the crystal without detonating it.
