[MC-276929] Vex with LifeTicks don't drop items on death

The bug

Once the "LifeTicks" of the vex have passed and it dies it won't drop it's items. I am not sure if this intended since it doesn't count as being killed however since it's default drop values are 0 this might not be the case.

How to reproduce

First encounter:

give @s minecraft:ender_dragon_spawn_egg[minecraft:entity_data={id:"minecraft:vex",LifeTicks:1,Health:1f,HandItems:[{id:"minecraft:netherite_sword",Count:1b},{}],HandDropChances:[1.0f,0.0f]}]

When removing the "LifeTicks" and just hitting it seems to work fine

give @s minecraft:ender_dragon_spawn_egg[minecraft:entity_data={id:"minecraft:vex",Health:1f,HandItems:[{id:"minecraft:netherite_sword",Count:1b},{}],HandDropChances:[1.0f,0.0f]}]
