Steps:

1. Add a web content folder and assign Single Approver Workflow to this folder.
2. Create a new user [email protected] and grant this user Administrator role (so that this user can approve the article).
3. Login as [email protected] -> Add a new web content into the folder created in #1 -> and Submit for Publication.
4. Login as [email protected] -> Approve the article created in #3.
5. Go to web content page and change the view to "List" view. 
6. Check the tool tip of "Approved" status.

Expected behavior: approver should be displayed.
Actual behavior: creator (test user) is displayed.
