Piglins shooting at you if you replace their weapon

Issue
A piglin holding a crossbow will shoot at you if you replace their item with a melee weapon.

How to recreate

1. Summon a piglin with either a spawn egg or "/summon piglin ~ ~ ~"
2. Ensure that the piglin you spawned is holding a crossbow
3. Use command "/replaceitem entity @e[type=piglin] slot.weapon.mainhand 0 wooden_sword"
4. Switch gamemode to "/gamemode s"

Expected outcome
The piglin should chase the player with their wooden sword.

Actual outcome
The piglin uses ranged attacks as if it were holding a crossbow, shooting mysterious arrows from their chest.
