Summary:
The arrow in the Stonecutter UI only appears after placing an ingredient. This only happens in the Classic UI Profile, and also doesn't match the similar blocks with arrows in the interface (Anvil, Grindstone, Cartography Table, Smithing Table).

Steps to reproduce:

1. Switch to the Classic UI Profile.
2. Place Stonecutter.
3. Open its interface.
4. Place a block (such as a stone) in the ingredient slot.

Observed results:
The arrow in the Stonecutter UI only appears when placing an ingredient.

Expected results:
The arrow should always be in the Stonecutter UI.
