When creating a split pane with one TextField control on the left. When the user moves divider to the left an exception is thrown the divider becomes locked or (won't move).

To reproduce:
1) keep the textfield blank
2) move divider as far left as you can.
3) observe the errors.


Attached is a simple test to reproduce the problem.

Here is a code snippet:

   @Override
    public void start(Stage primaryStage) {
        Group root = new Group();
        Scene scene = new Scene(root, 380, 118, Color.WHITE);

        // Left and right split pane
        SplitPane splitPane = new SplitPane();
        splitPane.prefWidthProperty().bind(scene.widthProperty());
        splitPane.prefHeightProperty().bind(scene.heightProperty());
        
        VBox leftArea = new VBox(10);
        leftArea.getChildren().add(new TextField());
        
        VBox rightArea = new VBox(10);
        splitPane.getItems().addAll(leftArea, rightArea);
        
        HBox hbox = new HBox();
        hbox.getChildren().add(splitPane);
        root.getChildren().add(hbox);
        
        primaryStage.setScene(scene);
        
        primaryStage.show();
    }
