Steps to reproduce:

1. Create a "Container" folder under the root content location
2. Under the "Container" folder create two folders:
   • Folder B
   • Folder A
3. Change "Sub-items sorting order" for the "Container" folder to "Content name", "Ascending".
4. Modify the Article type: add a new "Related folder" attribute with the following parameters:
   • Field type: Content Relation (single)
   • Starting location: "Container" folder
   • Allowed content types: Folder
5. Create a new Article content, and try to set the value for "Related folder" field.
6. UDW is shown with child folders of "Container" folder.

Expected result: first "Folder A" should be shown, and then - "Folder B". So child location should be sorted following changes made in step 3.

Actual result: "Folder B" is shown first, and changes made in step 3 are ignored.
