Lunge spear attribute swap after using a Wind Charge applies downward velocity instead of horizontal momentum in 26.4 Snapshot 8

Description:
When launching upward with a Wind Charge and immediately attribute-swapping to a spear enchanted with Lunge, an unexpected downward force is applied to the player. This causes the player to drop much faster than in previous versions and prevents them from covering normal horizontal distance. Performing the same Lunge spear technique after jumping off a ledge or cliff without a Wind Charge behaves normally.

Steps to Reproduce:

1. Equip a Wind Charge and a spear enchanted with Lunge in your hotbar.

2. Look down and use the Wind Charge to launch yourself into the air.

3. Immediately attribute-swap to the Lunge spear and trigger a jab attack while mid-air.

Expected Result:
The Lunge enchantment applies strong horizontal forward momentum, allowing the player to glide across a wide distance.

Actual Result:
A downward force pulls the player toward the ground, cutting airtime and horizontal travel distance short.
