The items in the trade select buttons of the villager ui are misaligned in height.

compare the alignment of the bow in my inventory with its alignment in the villager trade button.

You can see that the top leaves one pixel open in the inventory, and also one pixel on the trade button. This means that the item is positioned from the top of the button. However, from the top there are two pixels left, while there are none in the inventory.

I would expect that the items are centered, but they aren't. This looks also weird when an item texture reaches to the top of an inventory slot, as the top pixels of the item render on the edge of the button (look to the crossbow in the screenshot.)
