After JDK-8228363 has been integrated, menus and submenus in the border of the screen are no longer repositioned so they don't overlap (in terms of moving them to the other side of they parent menu). Now they are laid out fully within the screen, but with no offset to such border, but overlapping on top of their parent menu.

The attached test can be used to show the change. Up until OpenJFX 16-ea+7 there is no issue, while building from head shows it.
