In studio, "Preview" seems to not work in rerun course (GG101x)

Description

The course was created with the "rerun this course" feature.
https://studio.edx.org/course/course-v1:BerkeleyX+GG101x-2+1T2015

For units with unpublished content, "Preview" always takes the viewer to the page "PAGE NOT FOUND The page that you were looking for was not found. Go back to the homepage or let us know about any pages that may have been moved at technical@edx.org."

To me, it looks like the "preview" button is trying to take you to a link that looks like how the original course constructed link locations (i.e. .../courses/[course]/[number]....), not like how the new rerun course constructs link locations (/courses/course_v1:[course][number][run]...)
