sorting order problem (Date New -> Old)

[smallfish]

When I click the earlier product and sort by Date New -> Old. After return to the product listing screen, the clicked product will go to the 1st position. Also the same case for sorting Old -> New (But need to refresh screen).
http://demo.abantecart.com/shoes&sort=date_modified-DESC&limit=20 (try to click the 2nd, 3rd, 4th product and return back to the product listing screen).
Please fix it.
Thank you!
