Splash Potions Sometimes Go Through Entities

Steps to Reproduce:

• Summon Witch and push up against edge of a block, ensuring it can’t jump up

• Place Armour Stand on other side of that block

• Stand at least 4 blocks away from the Armour Stand

• Switch to Survival Mode to make Witch throw potions at you

Expected Behaviour:

• The potion hits the Armour Stand every time, protecting the player

Actual Behaviour:

• The potion usually hits the Armour Stand, but sometimes passes straight through, hitting the player instead
