Arrows hitting from above bounce off and get stuck on Creative players and invulnerable entities (Allay, Shulker and Enderman)

Summary:
Arrows collide with and get stuck on players in Creative Mode and invulnerable entities (specifically Enderman when there's nowhere to teleport to, closed Shulkers and Allays holding an item) when hitting them from above. When the arrow hits them, it gets stuck inside the hitbox, turns horizontal, and stutters. With a perfect direct hit, the arrow will never pass through the entity or player at all (as demonstrated in the attached screenshot using a summoned arrow).

In Java Edition, if an arrow hits a Creative player or invulnerable entity from above, it bounces off a few times and then falls through instead of getting permanently stuck inside the hitbox. This issue was not present in version 1.26.32.

Steps to reproduce:

1. Spawn a Shulker (wait for it to close), an Enderman (create a world entirely out of water and place one block of leaves) or an Allay (give it an item to make it invulnerable).

2. Stand directly under the entity (or have the entity perfectly aligned) and fire an arrow straight up so it hits the target on its way down from above.

1. (Alternative) Look directly upward in Creative Mode and fire an arrow straight up with zero charge so it falls back down perfectly onto your own hitbox from above.

Observed results:
The arrow collides with the Creative player, closed Shulker, Enderman or Allay from above. It fails to pass through, gets stuck in mid-air inside the hitbox, rotates horizontally, and stutters.

Expected results:
Arrows should not get permanently stuck inside hitboxes when hitting from above. They should fall through after bouncing a few times, matching Java Edition.
