Once you dye a shulker box, pressing space to repeat the same recipe (or just clicking on the recipe) will attempt to use the shulker box you've just dyed in the recipe despite it not being a valid crafting recipe.

Reproduction Steps

• Add a bunch of undyed shulkers to your inventory
• Give yourself a dye of any kind
• Use the recipe book to craft a dyed shulker
• Attempt to use the recipe book to craft another dyed shulker

Observed Results

• The recipe book attempts to use the already dyed shulker in the crafting table
