ArmorStandProjectile vanishes upon hit

[NightScythe1]

The ArmorStandProjectile class appears to lose its attached armour stand upon contact with a block/entity. This isn't really an issue for most spells which do end when the projectile makes contact, but for other spells in which the projectile is intended to pass through multiple blocks or entities with hit_count, it is a bit of an issue. Here's an example spell:

MD_icicle:
  actions:
    cast:
    - class: ArmorStandProjectile
      armor_stand_invisible: false
      actions:
        - class: Damage
  effects:
    tick:
    - location: target
      particle: end_rod
      particle_offset_x: 0.01
      particle_offset_y: 0.01
      particle_offset_z: 0.01
  parameters:
    target: other
    range: 24
    velocity: 12
    damage: 1
    hit_count: 10

if you try casting this at an entity, you'll see that the armour stand vanishes upon making contact, but the projectile itself continues through the entity as intended (shown via the end rod particle)
