Zombie nautiluses are neutral even while ridden by hostile mobs

Per the change log said:

Zombie Nautilus

• Zombie Nautilus is a new underwater mob that spawns with a Drowned rider wielding a Trident

• Zombie Nautilus is only hostile if ridden by a hostile mob

• Zombie Nautilus behaves similar to the Nautilus except that it cannot be bred

However when i’m tested it seems doesn’t work, player still require attack it to make it hostile.

to reproduce:
1. Summon a drowned rider
/summon minecraft:zombie_nautilus ~ ~ ~ {Passengers:[{id:drowned,equipment:{mainhand:{id:trident,count:1}}}]}
2. Let it attacking you
The zombie nautilus don’t attacking you until you hit it.
