I assume this is related to the inventory tweaks introduced in 1.16

I enjoy playing with controller in survival worlds, it's more relaxing and chill than leaning over my keyboard, however, one of the quality of life features seems to of been broken.

My controls are set up so that Y opens the inventory, and X opens Crafting. Whenever I open a world, the first thing I do is open my inventory using Y, and then I press RT to close the Recipe Book to reduce the screen footprint my inventory takes. It makes it easy to see mobs while I'm looking through my items, or in multiplayer environments- to see other players around me. Pressing X would then open my inventory with the recipe book open, and my cursor immediately in the book, ready to craft. This meant that only one button press was needed to get my inventory with, or without, the crafting menu. X would have a similar function to simply opening a crafting table (which still opens with the recipe book, much like pressing X with my controls used to).

The bug:
Inventory and Crafting buttons on controller are no longer separate and do the same thing
