RadioButtonGroup visualization bug?

I’m using Vaadin 14 and Java 11:

If I put a RadioButtonGroup in disabled mode, it does not refresh it’s value change on client side. Other components do.

Example:

  public MainView() {

    TextField textField = new TextField();

    RadioButtonGroup<String> radioButtonGroup = new RadioButtonGroup<>();
    radioButtonGroup.setItems("One", "Two");

    // init values
    textField.setValue("Tick");
    radioButtonGroup.setValue("One");

    //liteners
    textField.addValueChangeListener(
        e -> System.out.println("textField:" + e.getOldValue() + "->" + e.getValue()));
    radioButtonGroup.addValueChangeListener(
        e -> System.out.println("radioButtonGroup:" + e.getOldValue() + "->" + e.getValue()));

    //disable
    textField.setEnabled(false);
    radioButtonGroup.setEnabled(false);

    //action
    Button button = new Button("Do it!", e -> {
      textField.setValue(textField.getValue() == "Tick" ? "Tock" : "Tick");
      radioButtonGroup.setValue(radioButtonGroup.getValue() == "One" ? "Two" : "One");
    });

    add(textField, radioButtonGroup, button);
  }
