Vertical SplitPane: dividers doesn't render properly with style "-fx-orientation: vertical"

To reproduce run following code



import javafx.application.Application;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.SplitPane;
import javafx.scene.control.SplitPaneBuilder;
import javafx.scene.layout.StackPaneBuilder;
import javafx.scene.layout.VBox;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;

public class SplitPaneTest extends Application {

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

    private Parent getContent() {

        VBox list = new VBox();
        list.setManaged(false);
        SplitPane pane = SplitPaneBuilder.create().items(
                StackPaneBuilder.create().style("-fx-background-color:white;").children(new Rectangle(40, 40, Color.WHITESMOKE)).build(),
                StackPaneBuilder.create().style("-fx-background-color:white;").children(new Rectangle(40, 40, Color.BLUE)).build(),
                StackPaneBuilder.create().style("-fx-background-color:white;").children(new Rectangle(40, 40, Color.RED)).build())
                .prefWidth(150)
                .prefHeight(150)
                .build();
        pane.setFocusTraversable(false);
        pane.setStyle("-fx-orientation: vertical;-fx-border-color:red; -fx-background-color:green;");
        pane.setMaxSize(150,150);
        list.getChildren().addAll(pane);
        return list;
    }

    public void start(Stage stage) {
        stage.setX(100);
        stage.setY(100);
        Scene scene = new Scene(getContent(),800,300);
        stage.setScene(scene);
        stage.show();
    }
}
