Entities cannot be hooked by fishing rods if the line is cast while the player (or caster in general) is submerged in water.

Steps to Reproduce:

1. Spawn an entity underwater
2. Try and hook the entity with a fishing rod item

Observed Results:

The line will be cast, but will not latch onto the entity. Instead, it will function like you are normally fishing.

Expected Results:

The bobber would be able to latch onto the entity regardless of submersion.

Notes:

Considering the player is unable to fish while the bobber is underwater, it would make sense that the bobber function as it would above land when trying to hook an entity.
