Keep ComboBox on selected item on expand

[megalobrainiac]

When I create a simple combo box I see that, when I expand, it starts at the selected item but then scrolls to the top. Is there a way to keep it scrolled to the selection?

public class ComboBoxScrollToTop implements EntryPoint {

  @Override
  public void onModuleLoad() {
   SimpleComboBox<String> field = new SimpleComboBox<String>(new StringLabelProvider());
   field.setTriggerAction(TriggerAction.ALL);
   for (int i = 1; i < 100; i++) {
     field.add(String.valueOf(i));
   }
   field.setValue("90");
   RootPanel.get().add(field);
  }
}

I've moved this to our Bugs forum and opened an internal issue to track this - this can pretty clearly be reproduced on http://www.sencha.com/examples/

It appears I'm mistaken, and that this has been fixed - the issue that can be reproduced at the link above cannot be seen on the nightly build at http://staging.sencha.com:8080/examp...Place:combobox

Here's a workaround that seems to be a workaround in a 3.0.1 project:

   field.addExpandHandler(new ExpandHandler() {
    @Override
    public void onExpand(ExpandEvent event) {
      String selected = field.getValue();
      final int index = field.getStore().indexOf(selected);
      Scheduler.get().scheduleDeferred(new ScheduledCommand() {
        @Override
        public void execute() {
          field.getListView().getElement(index).scrollIntoView();
        }
      });
    }
  });
