When the wither's health drops to half or below, conventional projectiles such as arrows and tridents fail to cause damage. However, wind charges do not adhere to this limitation, which may be an intentional design choice.

Steps to replicate

1. Invoke the presence of a wither
2. Reduce its health to half or below
3. Launch wind charges towards it

Observed behavior: The wind charge is capable of inflicting damage,
Expected behavior: The wind charge should not be able to cause damage.
