Projectiles thrown while in a minecart spawn in the wrong location

While riding a Minecart, thrown projectiles spawn in the wrong location. Instead of coming from the player's head, they spawn ahead of the player. The faster the Minecart moves, the more off the projectile's position becomes.

Steps to Reproduce:

1. Enter a Minecart.
2. Start moving the Minecart.
3. Throw any kind of projectile

Observed Behavior:
Projectiles spawn ahead of the player, making it almost impossible to hit targets. The faster the Minecart, the worse the issue.

Expected Behavior:
Projectiles should originate from the player's head.

Impact:
This bug makes hitting anything while in a Minecart nearly impossible and breaks custom maps relying on Minecart projectile mechanics.
