Affects Version/s: Minecraft 18w19a
Fix Version/s: None
Hold a water bottle or a potion.
The animation seems to bounce up and down repeatedly, as if it was being spammed or something. When you try to drink it, there is no animation and the sound is a little glitchy but the potion still functions normally.
Happens in offhand slot as well.
Works with splash and lingering potions.
Does not occur with empty bottles, milk, or any food.
