[1.16.5 Bug] Unexpected behavior of entity health

Minecraft 1.16.5 Forge 36.2.35 Mod 0.6.4

If the max health of an entity is modified by using "entities.modifiers", for example: 
`modifiers = ["minecraft:pig;minecraft:generic.max_health;2;0"]`
It will always has max health regardless whether its health has been specified.
Which means, run command `summon minecraft:pig ~ ~ ~ {Health:1}` can never summon a pig with 1 health, but only 12 health.
