Stairs craft with ratio that isn't right. Stairs are 3/4 smaller than blocks, but are crafted with ratio of 3 blocks = 2 stairs, meaning stairs are even more expensive than blocks.

What I expected to happen was...:
Stairs recipe should have 8 stairs as output.

What actually happened was...:
Stairs recipe gives 4 stairs.

Steps to Reproduce:
Not very hard, just try to craft stairs, I guess...
