Projectiles do not register a margin-assisted entity hit through a block collision shape change

Since 1.21.11 a projectile can no longer register a margin-assisted entity hit through a solid block, even if a change to that blocks collision shape would have exposed the target entity to the projectiles hitscan.

Steps to reproduce:

  1. Build the setup shown in the included image

  2. Add the following command to the command block:

    summon minecraft:wind_charge ~ ~1.25 ~
  3. Use a bow to shoot an arrow into the middle of the top surface of the trapdoor.

  4. Right click the noteblock.

❌ In 1.21.11 the hit on the entity below the trapdoor does not register.

✔ In all prior versions the hit on the entity is registered and the wind charge begins to move.
