Tag set search criteria does not persist

Searching for a tag set tag does not persist to search actions. The search results recordset is restricted to records with the searched for tag. However the tag criteria is not shown in the the edit search criteria area. Using the task combo box to perform an action on the search results (smart group, export etc) causes the action to be performed on a recordset that does not include the tag criteria.

This behaviour does not occur when searching with "standalone" tags that are not in a tag set.
