Changes in Scene + TreeItem + Focus

Question

In my application, I frequently change the contents of a BorderPane or other container to switch between various views. These new views often need to get the focus (for easy keyboard control).
I've found however that when this involves a TreeView where I want the first item to have the focus that this is not working properly, see this example:
public class TreeItemFocusTest extends Application {
  public static void main(String[] args) {
    Application.launch(args);
  @Override
  public void start(Stage primaryStage) throws Exception {
    VBox vbox = new VBox();
    BorderPane borderPane = new BorderPane();
    Button button = new Button("Sometihng to grab focus");
    final TreeView<String> treeView = new TreeView<String>();
    TreeItem<String> root = new TreeItem<String>("Root");
    root.setExpanded(true);
    treeView.setRoot(root);
    root.getChildren().add(new TreeItem<String>("Item 1"));
    root.getChildren().add(new TreeItem<String>("Item 2"));
    root.getChildren().add(new TreeItem<String>("Item 3"));
    root.getChildren().add(new TreeItem<String>("Item 4"));
    vbox.getChildren().addAll(button, treeView);
    Scene scene = new Scene(borderPane);
    primaryStage.setScene(scene);
    primaryStage.show();
    // Change the borderpane contents here
    borderPane.setCenter(vbox);
    // Give desired item the focus
    treeView.requestFocus();
    treeView.getFocusModel().focus(1);
}The TreeView itself gets the focus, but the TreeItem #1 does not get the focus.
I've found two work-arounds (that will give TreeItem #1 the focus as expected) :
1) Always replace the entire scene
2) Wrap the focus calls in Platform.runLater()
Neither seems to be the correct behaviour to me. Anyone care to comment or knows of a better solution?
