Calling of {{TextArea.setPrefRowCount(n)}} does not affect calculated control height.

The simplest code example:
{code}
    public void start(Stage primaryStage) {
        Group root = new Group();
        Scene scene = new Scene(root, 300, 250);

        TextArea test = new TextArea("text here");
        test.setPrefRowCount(1);
        root.getChildren().add(test);

        primaryStage.setScene(scene);
        primaryStage.show();
    }
{code}
Here control height is about 5 rows, when I want only 1 row.
