The bug

The crafting recipe availability does not update when your inventory changes.

How to reproduce

1. Place a log block in the crafting grid
2. Open the crafting help
3. Have the recipe for planks shown
   → The recipe should be red since you do not have the log block in your inventory
4. Move the log block from the crafting grid to your inventory
   → You will notice that the recipe remains red until you switch pages or reopen your inventory
