Shift clicking a netherite ingot into a smithing table moves it into the gear slot

When you shift click a netherite ingot into a smithing table, it gets moved into the gear slot rather than the second slot. This also relates to MC-185777, because java had this bug.

How to reproduce:

1. Place a smithing table
2. Shift click a netherite ingot
   It is at the gear slot.
