Steps to reproduce:

1. Get a trident (Haven't tested this on an unenchanted one but my trident had Impaling V, Unbreaking III, Loyalty III, Channeling and Mending)

2. Try and use the trident as a ranged weapon.

Expected result:

The trident should be thrown as a projectile.

Observed result:

The charging animation will culminate as if you have thrown the trident but it will quickly go back in your hand but it doesn't take durability damage meaning the trident never really got thrown.
