REST Api for Get Landing Page by ID does not return "Approved with Draft"

We are seeing that in the Marketo UI, the status for a landing page is "Approved with draft"

But...when we fetch the details of that landing page by ID , we see that the the status is "Approved".  It seems that a new page that has never been approved returns a status of "Draft",  but once you approve the page, you only get back a status of "Approved" even if it has a Draft.  

This kind of limits the usefulness of the API, since our goal is to find all pages that are in Draft, whether they have ever been approved or not.
