Scenario: ReactiveCommand executes a network request hat can throw an exception. View subscribes to the ThrownExceptions property so it can display a toast message e.g "Request failed"
The user executes the command, but immediately goes to another view, so the current view is destroyed and unsubscribes in WhenActivatedfrom the command.
The network request throws a few seconds later, but since there is no subscriber to ThrownExceptions, the application blows up.
