ScrollPane прокручивается сама по себе

Question

У меня есть экран, на котором компонент root - это ScrollPane. Однако когда диалоговое окно открыто, полоса прокрутки уже прокручена до конца. Я проверил, что getVvalue() вернул во время initialize(), и это было 0. Я пробовал использовать setVvalue() как для 0, так и 1 в initialize(), но ни один из них не работал.

Main. java:

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        Scene scene = new Scene(new ScrollableDialog(), 1024, 768);
        primaryStage.setScene(scene);
        primaryStage.show();
    }


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

ScrollableDialog. java:

public class ScrollableDialog extends ScrollPane {
    public ScrollableDialog() {
        FXMLLoader loader = new FXMLLoader(getClass().getResource("/pkg/lib/fxml/scrollable-dialog.fxml"));

        loader.setRoot(this);
        loader.setController(this);

        try {
            loader.load();
        } catch (IOException exception) {
            exception.printStackTrace();
        }
    }

    @FXML
    public void initialize() {
        System.out.println(getVvalue());
    }
}

Как видите, используется еще один пользовательский компонент, FormEntry. Вот оно:

FormEntry. java

public class FormEntry extends VBox {
    @FXML Label keyLabel;
    @FXML Label valueLabel;

    private String keyText;
    private String valueText;

    public FormEntry(@NamedArg("keyText") String keyText, @NamedArg("valueText") String valueText) {
        this.keyText = keyText;
        this.valueText = valueText;

        FXMLLoader loader = new FXMLLoader(getClass().getResource("/pkg/lib/fxml/form-entry.fxml"));

        loader.setRoot(this);
        loader.setController(this);

        try {
            loader.load();
        } catch (IOException exception) {
            exception.printStackTrace();
        }
    }

    @FXML
    public void initialize() {
        keyLabel.setText(keyText);
        valueLabel.setText(valueText);
    }

    public String getKeyText() {
        return keyText;
    }

    public void setKeyText(String keyText) {
        this.keyText = keyText;
        keyLabel.setText(keyText);
    }

    public String getValueText() {
        return valueText;
    }

    public void setValueText(String valueText) {
        if (valueText == null || valueText.isBlank() || valueText.isEmpty()) {
            this.valueText = "-";
        } else {
            this.valueText = valueText;
        }

        valueLabel.setText(this.valueText);
    }

    public void setValueText(int number) {
        this.valueText = String.valueOf(number);
    }
}

У вас есть представление о том, что может быть причиной этого?
