Being in the "Throwing a Trident" Phase while entering a portal destroys the trident upon teleportation

When in the "about to throw trident" animation, teleporting to another dimension removes the trident from the player's inventory & effectively erases it from the world.

This was confirmed by searching for all thrown_trident entities in the world; the trident no longer existed. This does not affect gateways or enderpearl teleportation, as long as the teleportation is within the same dimension.

To reproduce, simply step into a portal while aiming your trident & it will disappear.
