When giving the player Levitation and quickly clearing the effect, snowballs will be thrown straight up instead of the way the player is facing.
Steps to reproduce:
Set up command blocks that give the player minecraft:levitation for 1 second, set to 255 amplifier, then take it away after a short pause.
Throw snowballs repeatedly while this happens, and they will behave incorrectly.

Can you reproduce this issue with a level of levitation less than 4?
How is this a duplicate of that issue? It seems only tangentially related to that issue.
