Items with their swing_animation type set to "stab" will bob up and down on attack

Despite setting the swing_animation type parameter to “stab”, it still bobs and down

How to replicate:

1. /give @s golden_sword[minecraft:swing_animation={type:"stab"}]

2. Swing the sword

3. Notice how the sword still bobs up and down

Note. For some reason, this “up and down” bobbing is tied to piercing_weapon and not swing_animation
