Trade Inventory Bug with shift click

This affect Villagers and Wandering Trader, in trade inventory the shift click only return one item in trade, if you dont use the shift you can get more items, in any cases the inventory show "ghost items"... like the item duplicate but disapear in the next tick.

 

Example:

• Spawn a Wandering Trader
• Put emeralds
• Shift click for get items
• Expected: return 4 items for the trade (in cases of the item is stack return 4 stacks)
• Result: return only one item for the trade
