    Fix for bug 746400 - Speak child position breaks Qt menu item presentation
    
    This regression was introduced by the fix for bug 746086. isLayoutOnly()
    was checking for dead accessibles. When we stopped calling it, we stopped
    doing this sanity check. And there are dead accessibles in certain Qt menus.
