I have an editable ComboBox and I want to add to items the values an user enters. However, when items list is changed then the text in ComboBox editor also changes.

This is my code:

public class JavaFxTest7 extends Application {

    @Override
    public void start(Stage stage) {
        var list = List.of("A", "B", "C");
        var comboBox = new ComboBox<String>();
        comboBox.setEditable(true);
        comboBox.setItems(FXCollections.observableArrayList(list));

        var button = new Button("Push Me");
        button.setOnAction(e -> {
            comboBox.getItems().add(0, comboBox.getValue());
        });

        Scene scene = new Scene(new VBox(comboBox, button), 400, 200);
        stage.setScene(scene);
        stage.show();
    }

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

and this is a result:

Could anyone say if this is a bug or I am doing something wrong?
