When menu is changed by inserting or removing items and submenu is open,
menu size can change become inconsistent with submenu position. We may
need to recursively relayout submenus when menu size is changed or menu is
scrolled. Note that submenus relayouting is not trivial, just reposition
can cause submenus going outside of screen. Screen height submenus with
scrollers should be not moved vertically. When changed menu width
increase, submenus may go out of screen horizontally and need to change
open direction.
As I understand, other OS do not implement this feature and I am not sure
that it is required as it can be annoying. This feature need no be
discussed.
