Projectiles go through an entity if it is close to a player or a snow golem

This issue relates/blocks to MC-88491.
Comment link

I can't reproduce this or MC-88491 in 18w11a. Would someone else care to try to confirm?

MC-88491 is blocked by MC-122335.
MC-88491 can be parsed as cannot reproduce until MC-122335 is fixed.

Yes but I can't reproduce MC-122335 either. Were you able to?

I can reproduce.

Arrows are effected I found the bug myself

use the contraption used in the last link I posted and it goes straight through the player

This issue has been fixed in 20w06a.

This is not entirely fixed but I'm not sure if a new issue should be opened or not.

This still occurs in the following situations:

• If the project entity is created inside of another entity it ignores collisions with that entity. For example when throwing a snowball or ender pearl while your hitbox is slightly clipping inside another entity the projectile won't collide with this other entity. The entity's hitbox size is irrelevant here. This works even using a giant.

• Projectiles created by the player can still ignore collisions with the player that created them even after the projectile leaves the player's hitbox and collides with it again shortly after. This is most noticeable with arrows and splash potions, especially when throwing them straight up. The easiest way to reproduce this is by sneaking over the edge of a block while in at least 3 deep water and throwing a splash potion straight up. The splash potion will travel up, go outside of the player's hitbox, fall back down, completely ignore collisions with the player's hitbox, and continue sinking down in the water until it lands on a block below.
