- macOS only
- shifting vertically only
- by what sounds like the height of a menu bar group

I would check the menuBar property of those stacks.

Also, generally better when doing layout stuff to work with card 
coordinates rather than stack coordinates, as the latter may be shorter 
than the former if a menuBar group is active on macOS.
