5. Hit the "invite player" button.
6. Now press the "cancel" button and take note of how the "Remove" and "Operator" buttons are still visible and still can be interacted with, therefore indicating that the "Remove" and "Operator" buttons in the realms "Players" menu still function despite no player within the list being selected.

Observed Behavior:

The "Remove" and "Operator" buttons in the realms "Players" menu still function despite no player within the list being selected.
