// This test is to check that the menus in a menubar are displayed correctly in both the top and
// bottom cases. Especially when using multiple screens. If possible relayout the screens in order
// to have one that is entirely in negative coordinates (i.e. the primary starts at 0x0 and the
// secondary is above it).
