Removing the Pillager's Crossbow using commands, makes it still shoot arrows.

Removing the Pillager's Crossbow using commands, makes it shoot arrows from it head, and it shoots it very quickly even though the mob has no equipped Ranged Weapon.

Expected when Crossbow has been removed:
Becomes Passive/Neutral or still Hostile (attacking using it's hands).

Result:
Still shoots arrows very fast.
