* Reproducing bug #12943 where an action on a Button or ComboBox placed at the
* bottom of a window in a scroll panel, will scroll up the parent panel.
*
* This was due to the fact that with the state confirmation notification from
* the server, the window.setVisible would be call again, and the hack that
* solved the scrollbars in a window (#11994) would cause the our bug.
