The new wind charge item is blocked by non-solid blocks like short-grass, ferns, flowers, etc. Because you need to hit an entity's feet with a wind charge in order to get any significant knockback, short grass gets in the way constantly. No other projectiles in the game behave like this, even similar ones like snowballs/eggs, so I believe this is a bug.
