When a Drowned with a Trident loses it's target, instead of lowering it's arms and de-aggroing, it will throw a trident at it's feet first before doing so, which was a behaviour they did not have prior to 1.18

Video proof of this can be seen here: https://mega.nz/file/EJYEkJQI#jK967RpR_V5jfZq7lGKcKf7nkYSgpkMSc2grwB7wbWc 

Steps to Reproduce:

1. Have a Drowned with a Trident aggro you, another player, a villager, or a Wandering Trader and have it's target move away from the drowned but not far enough way to where it de-aggros immediately.
2. Apply the invisibility effect to the Drowned with Trident's Target via command, potion, or other means depending on who the target is.

Observed Results:

The Drowned with the trident will throw one at it's feet a split second before lowering it's arms, doing a melee animation, and de-aggroing once it catches up to where the Target (now invisible or invalid via out of range) last was.

Expected Results:

The drowned with the Trident should immediately de-aggro upon it's target becoming invisible or invalid (like it did in 1.17 and back) and not throw a Trident at it's feet beforehand.
