Drowned is passive towards the player out of water

A Drowned was spawned in by a certain command, but was unresponsive to the player...

[The world is in survival, gamerule mobgriefing was set to true, Cheats was turned on]

Command used for spawning drowned-

/summon drowned ~ ~ ~ {Invulnerable:1,PersistenceRequired:1,Silent:1,CanPickUpLoot:1b,ActiveEffects:[

{Id:18,Amplifier:0,Duration:999999}

]}

It is guaranteed that the drowned can see the player, but won't attack it unless the drowned 

The Drowned is attacking baby turtles and smashing eggs, but not attacking the player unless the player and the drowned both are in water... if the player comes out of the water after it attacks, it keeps on attacking... Unless we switch to creative and back to survival again
