Splash potions are broken / All thrown potions are water potions

When I tried to throw a splash potion of harming it didnt hurt mobs/me. Also tried with splash potion of leaping

Comment by [Mod] Skylinerw on MC-92554:

Happens with all default and custom potions; the item data from the inventory potion is not stored on the ThrownPotion (defaulting to splash_potion with no effects, as well as a "ThrownPotion entity # has no item?!" error in log).
