Steps to Reproduce:
Place a stonecutter
Open stonecutter GUI
Input a block with more than one page of crafting options, e.g. Tuff
Scroll down
Select a crafting recipe
Take the item out of the stonecutter
Observe how your scroll position was reset
With more and more crafting options and blocks added, this bug becomes more and more common with every addition, and makes crafting things that aren't on the first stonecutter page very annoying.
