Profiles with smart group restriction -- search detail view does not list groups

1) Create a profile and in the settings restrict it to a smart group.
2) Add fields to the profile, including Groups.
3) Run the search and select one of the results to view details.
4) The Groups field is empty.

This behavior only seems to occur when the profile is restricted to a smart group. If it's restricted to a static group, the groups are listed on the detail view.
