2. Enable Single Approver Workflow for Web Contents
3. Submit 3 Web Contents for publication
4. Go to My Workflow Tasks > Assigned to My Roles
5. Click on "Filter and Order", select "Completed", 0 results will appear as there were no completed workflow tasks so far.
6. Check the "Filter and Order" and arrow up/down (ascending/descending ordering icons), hover the mouse on them:

Actual behavior: Both buttons will be disabled (the HTML element will have a disabled attribute within:
