Crafting consumes items, delivers random duplicate inventory item instead of crafted item.

Intermittent issue. This has happened twice since 1.1.17.2 upgrade. 

The last time this happened I was making deepslate brick stairs. I had 4 stairs in the leftmost hotbar slot. When I crafted the stairs, the deepslate bricks were deducted from my inventory but I still only had 4 stairs on the hotbar. I checked my inventory and discovered a second iron bucket ( not stacked) in my inventory.
