ChoiceBox does not display a selected item value which is not in the items list

ChoiceBox docs state "it is possible for the developer to specify the selected item to be something other than what is available in the predefined list".

Example code:

public class ChoiceTest extends Application {

    @Override
    public void start(Stage stage) throws Exception {
        ObservableList<String> list = FXCollections.observableArrayList("A", "B", "C");
        ChoiceBox<String> choiceBox = new ChoiceBox<>();
        choiceBox.getSelectionModel().select("D"); // or choiceBox.setValue
        choiceBox.setItems(list);

        stage.setScene(new Scene(choiceBox));
        stage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

The result is that the displayed item is blank. A quick look shows that ChoiceBoxSkin is set to display "" when selectedIndex = -1, which is the value for a selected item which is not in the list of items.
