A decision block that await change in status or navigation bar visibility.
The fiber will pause until status or navigation bar visibility has changed,
proceeding through the YES path if a selected visibility mode is activated,
proceeding through the NO path if deactivated.
Note! Android currently do not allow access to the currently active mode,
hence it’s not possible to implement a proceed option, also expect seemingly unintentional but valid triggering.
- Visibility — visibility mode to await, default is any.
