Bloop 82fe5ef96e Makes puzzle elements unable to have their icons messed with (#76348) ...

## About The Pull Request

The hand labeler (and any other item that is capable of calling
`update_appearance` on an atom) was erasing the overlay icon when used
on a sliding puzzle piece. This just stops that from being able to
happen.

There should never be a case when the puzzle icon or overlays get
changed outside of during `set_puzzle_icon()`.

The puzzle is still able to be completed if any of the pieces get
labeled, by the way.
