title: JavaFX TextInputControl requestFocus
body: <p>I'm trying to call requestFocus method from a TextInputControl. Without success.
  I want to set focus on a TextInputControl when I open a new Tab. I'm doing this:</p>
  
  <pre><code>tab.setContent(anchor);
  tabPane.getTabs().add(tab);
  
  SingleSelectionModel&lt;Tab&gt; selectionModel = tabPane.getSelectionModel();
  selectionModel.select(tab);
  
  focusTopLeftInputArea(anchor);
  </code></pre>
  
  <p>and focusTopLeftInputArea find a TextInputControl "ti" and call ti.requestFocus().</p>
  
  <p>focusTopLeftInputArea works fine finding the TextInputControl but the control doesn't get focused.</p>
