/**
 * A PopupPanel that can appear over Flash movies and Java applets.
 * <p>
 * Some browsers have issues with placing a &lt;div&gt; (such as that used by
 * the PopupPanel implementation) over top of native UI such as that used by the
 * Flash plugin. Often the native UI leaks over top of the &lt;div&gt;, which is
 * not the desired behavior for a dialog box.
 * <p>
 * This implementation hides the native resources by setting their display
 * property to 'none' when the dialog is shown, and restores them back to their
 * prior setting when the dialog is hidden.
