[MC-302171] Instant Health Level n*32

Instant Health potions with amplifier A = n * 32 - 3, (levels 29, 61, 93, 125, 157, 189, 221, 253) kill entities as the calculation 4 << 29 produces a negative value and thus adds negative HP to the entity’s health. Amplifiers A = n * 32 - 2 and A = n * 32 - 1 have no effect as 4<<30 and 4<<31 produce 0. Same thing happens when using instant Damage on undead mobs as the same calculations are used.

This is clearly a bug wdym? This is not a suggestion or feature request. Health potions on a specific Level kill the player and entities. This is not how it is supposed to be, why would it not be a bug when a healing item kills you?
