Steps to Reproduce:
- Enable the Next Major Update experimental toggle;
- Place any sign that's not made from oak;
- Try to edit it;
- Quit the world and enter again;
- Try to edit the sign.
Upon reload, every sign will display the oak sign texture, regardless of which type of wood it's actually made of.
The editing screen always matches the type of sign that's being edited.
