The Recipe Book button in GUI screens can be focused using the Tab key; however, while the book is open, you cannot then focus the components in the Recipe Book such as the Search box and the Showing All/Showing Craftable button using the Tab key.

Steps to Reproduce:

• Open a GUI with the recipe book (such as the crafting table or furnace)
• Focus the Recipe Book by pressing Tab
• Press Space to open the Recipe Book
• Press tab again
  • Nothing happens
