So perhaps a better way to resolve this situation is to teach 'undo'
about drag-and-drop, so that it doesn't undo selectively immediately
after drag-and-drop?

IOW, the selective undo feature AFAIU assumes that the region is set
up by the user before invoking 'undo', and that is not so in this
case.
