[2.0 Trunk] Menu width shrinks when submenu is displayed
Run the "ToolBar & Menus -> Basic ToolBar" explorer demo against the 2.0 trunk. Open up the "Button w/menu" button and then one of its submenus. The main menu shrinks when the submenu opens. Although not demonstrated by the explorer demo, the main menu keeps on shrinking if you open further subsubmenus. Screenshots attached.
