To reproduce:

1. Start with recipe book closed and inventory closed
2. Open inventory with inventory open/close key (default "e")
3. Open recipe book by clicking on book icon
4. Click on search filter field next to magnifying glass icon
5. Press inventory open/close key (default "e")
6. Observe that the inventory screen closes instead of typing letter "e"

This also affects the Crafting Table (but not furnace, blast furnace, smoker).

The issue does not arise if Recipe Book is already open upon opening Inventory.
