True for cards, but not for stacks (a substack can be any size; it's not
dependent on its main stack's size).

It's a consequence of the way cross-platform menus are handled. On Windows
and Unix, the menu bar appears in the top of the window. On Macs, it's
placed at the top of the window, but since it doesn't need to actually
appear there - since the Mac uses a separate menu bar - the stack is
resized and scrolled up so the group is hidden on that platform. That way,
the same stack can be used on all platforms without changes.

Check out the "editMenus" property in the Transcript Dictionary, and the
"About menus and the menu bar" topic, for more background on this.

(The next version of Rev will automatically place a menubar group created
with the Menu Manager on all cards, and I've added some
strategically-placed comments on this to the docs, so this should cause
less confusion.)
