Based on 1.11.2 decompiled using MCP 9.35 rc1
The methods overriding net.minecraft.inventory.Container.transferStackInSlot(EntityPlayer, int) return an empty item stack if an item is valid for a slot but cannot be placed in it, for example because there is already an item in the slot. Instead it should try all other valid slots before returning an empty item stack.
