If you click on the background of a recipe book group list, the window of all the entries will close.
Steps to Reproduce:
Give the player any set of items which allows for a recipe book group to show (ex; various wood planks)
Inside a crafting bench, right click a recipe group to open it
Click on the background texture of the group (not a recipe entry)
Observed Behavior:
The group window will close.
Expected Behavior:
Nothing should happen because the background is part of the window, and it is very easy to accidentally click the background when aiming for a recipe entry in the list, leading to the player unintentionally closing it.
It would be expected that clicking anywhere outside of the entire group window would close it.
Could be intentional but I still can confirm.
