This is even stranger. When your turn starts and you get to promote at the start, then the button to rollback is available. It should not be available and it correctly does nothing.

After you have promoted, the button could arguably be available (It is your time after all so why not do a different decision) - But it is not available.

Now after you lift a piece, the option becomes available and fully rolls back your move including the promotion at the start.
