Steps to reproduce:
- Login as a user or admin
- Hover over "Wiki" and click on "Document Index"
- Sort elements in the table by "Page" ascending
- Sort elements in the table by "Page" descending
I've attached screenshots for both cases. I should mention that all the pages that are not sorted (fa - testul) are sorted corresponding to the little arrow (asc/desc), but they just aren't mixed with the other pages. Also I've performed actions on all the pages from that group such as: edit, copy, rename etc.
This bug also reproduces on the "Space Index" page.
Tested on Firefox 18.
