code: void initializeFormRenderer(Form form) {
      getChildren().clear();
      preferencesFormRenderer = new PreferencesFxFormRenderer(form);
      getChildren().add(preferencesFormRenderer);
    }
docs: Initializes the {@link PreferencesFxFormRenderer}.
  
  @param form to be rendered using the {@link PreferencesFxFormRenderer}
  @implNote This can't be done in the constructor, since the form has to be initialized by the
  corresponding presenter first.
