[Vanilla Clients] Cartography table doesn't show empty maps in result slot

You can still get the empty maps by clicking the result slot, it just won't preview

This now fully works when the mod is installed client-side.

On vanilla clients the copy Atlas shows correctly, but the empty map removal doesn't. Unsure if there's any way we can get this behaving correctly on vanilla clients.
