setManaged=false doesn't work
<p>I use following code:</p>

<pre><code>&lt;VBox fx:id="v" xmlns:fx="http://javafx.com/fxml" managed="false" prefWidth="100" prefHeight="100"&gt;
    &lt;Label text="label"/&gt;
&lt;/VBox&gt;
</code></pre>

<p>and the screenshot is:

<p>the text "label" still exist, how to make VBox disappear and remove its space, If i use Parent#remove, i cannot restore it</p>
