Strange Selection in TreeView

Question

Hello,
I am having some issues with TreeView. If attached code is run and the following tried
1. expand "RootNode"
2. expand "package B"
3. select either "B1" or "B2"
4. expand "package A"
Then there will be 2 tree items selected, either "B2" and "A3" or "B1" and "A2". The treeview has the selection mode set to single. Does anyone know what is causing this?
import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.scene.control.TreeView;
import javafx.scene.control.TreeItem;
import javafx.scene.control.SelectionMode;
public class Main extends Application {
     public static void main(String[] args) {
        launch(args);
    @Override
    public void start(Stage primaryStage) throws Exception{
          primaryStage.setTitle("TreeView Test");
          primaryStage.setScene(createScene());
          primaryStage.show();
     private Scene createScene(){
          StackPane stackPane = new StackPane();
          TreeView treeView = new TreeView<String>();
          treeView.setRoot(createModel());
          treeView.getSelectionModel().setSelectionMode(SelectionMode.SINGLE);
          stackPane.getChildren().add(treeView);
          return new Scene(stackPane);
     private TreeItem<String> createModel(){
          TreeItem<String> root = new TreeItem<String>("RootNode");
          TreeItem<String> packageA = new TreeItem<String>("package A");
          packageA.getChildren().addAll(new TreeItem<String>("A1"),new TreeItem<String>("A2"),new TreeItem<String>("A3"));
          TreeItem<String> packageB = new TreeItem<String>("package B");
          packageB.getChildren().addAll(new TreeItem<String>("B1"),new TreeItem<String>("B2"),new TreeItem<String>("B3"));
          root.getChildren().addAll(packageA,packageB);
          return root;
}

Hi. There is a similar bug on jira: http://javafx-jira.kenai.com/browse/RT-25514 (Two focused tree cells while there must be only one).
You may want to comment on it including your case.
