Lingering potions not creating area effect cloud on the ground

The bug

Lingering potions thrown on the ground can produce area effect clouds at varying heights. This behavior occurs from all kinds of throwing angles, distances, and speeds. This bug could be sufficiently fixed by fixing MC-88368.

Short entities like axolotls and turtles can sometimes avoid lingering clouds just because the cloud spawns so high, even though the potion landed on the ground. Example: MC-210987

How to reproduce

Press F3+B and throw several lingering potions on the ground. You can clearly see that some hitboxes are higher than others, often floating nearly half a block off the ground.
