2. Configure Single Approver for Wiki
3. Submit a Wiki page for publication
4. Move the Pending Wiki page (it's under the drafts tab) to the Recycle Bin
5. Empty the recycle bin

Expected result:
Emptying the bin will delete the Wiki Page

Actual result:
The wiki page cannot be deleted. Actions > Delete in the Recycle Bin will not work on the page either.
