By default a ContextMenu SHOULD do what you describe - always position
itself inside the boundaries of the browser's viewport. This feature
is made possible by the "constraintoviewport" configuration property of
Menu's superclass: YAHOO.widget.Overlay. However, there was a bug in
version 2.2.2 of Menu that crippled the "constraintoviewport"
functionality. This has been fixed in 2.3.
