Piglins can hold up crossbows to fire with no arrows loaded if interrupted whilst loading them

I caught a piglin holding up its crossbow as to fire at a hoglin beneath it. The piglin, however, had no arrows loaded into its crossbow and still held the crossbow, trying to fire at a hoglin without an arrow.

I believe this happened because it was interrupted whilst trying to load its crossbow because just earlier I had given him a gold ingot while he was loading his crossbow.
