Bug Piglin e Pillager

Pillager and Piglin when they are taken out crossbow and bow they keep shooting arrow.  See that when I removed the crossbow and bow weapons they keep shooting arrows as if they had these respective items. In the first video I put "/replaceitem entity @e slot.weapon.mainhand 1 air" to remove the item.  In the second video I died from an arrow even though they weren't holding anything
