Issue description

In 0.11.3, copying a slate with a pattern on it gives a pattern slate with said pattern in it
In 1.21.1, copying a slate with a pattern on it gives a blank slate

Steps to reproduce

1. Place down a patterned slate
2. Use the Copy Block keybind on it
3. Notice how you have a blank slate

Other information

You may hold down Ctrl when copying a slate to get it with its pattern, but that always makes a new stack of the item, (instead of trying to find a matching item first) which can be difficult to manage when working on spell circles
