Java SE (Java Platform, Standard Edition)

I call setStyle("-fx-font-weight: bold") with a label - the label's text is output in bold.
Then I call setStyle(null) with the same label - expecting that now the label's font is back to the definition from the CSS.

But: the label does not show a normal font now - it is still bold.
I have to explicitly call setStyle("-fx-font-weight: normal") in order to bring it back to normal font.

Is this a bug or a feature?
If this is a bug, then I will post a Jira-message, but I am not yet 100% sure...

My FX version is 2.2.

Thanks + regards!

Some example code:

package ztest;

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.SceneBuilder;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class Test_62_FontStyle 
    extends Application
{
    public static void main(String[] args)
    {
        launch(args);
    }

    boolean m_bold = false;
    VBox m_vb = new VBox();
    Label m_la = new Label("Some text to be styled.");
    Button m_bu = new Button("Change");
    
    @Override
    public void start(Stage primaryStage)
    {
        final Scene scene = SceneBuilder.create()
        	.root
        	(
        		m_vb
        	)
        	.build();
        
        m_vb.getChildren().add(m_la);
        m_vb.getChildren().add(m_bu);
        
        m_bu.addEventHandler(ActionEvent.ACTION,new EventHandler<ActionEvent>()
        {
            @Override
            public void handle(ActionEvent paramT)
            {
                m_bold = !m_bold;
                if (m_bold == true)
                    m_la.setStyle("-fx-font-weight: bold");
                else
                    m_la.setStyle(null); // does not reset font!
//                    m_la.setStyle("-fx-font-weight: normal"); // this works fine...
            }
        });
        
        primaryStage.setScene(scene);
        primaryStage.show();
    }
    
}
