It's actually the standard window event handler which is supposed to
prevent this.

No, it really is the Window Manager, not the standard window event handler.

When you call DragWindow (which is a Window Manager API), the DragWindow implementation prevents you from dragging the window's title bar underneath the menubar. It doesn't matter whether your window has the standard window handler or not.

If you override the standard event handler's behaviour, or don't use it
at all, then this can easily happen.

Actually, no, overriding the standard window event handler should make no difference. The only way I know of that you could break this would be to override kEventWindowBoundsChanging and explicitly modify the current-bounds parameter to be underneath the menubar.
