Losing the last viewed page when navigating away from a list of paged results

When browsing through pages of results, I can’t go back, with the browser back function, to the same page, after going to another.

For example, when I browse the users list for a Ladder, to choose who to challenge, I lose the page where I’m at after making a challenge.

I want to find a player who I can challenge, so I go to the last page of the ladder - lets say 44. Then I move page after page backwards and challenge a player from page 40. The site moves me to the game and if I hit the back button of the browser, to keep searching for a new challenge, I’m not at page 40 any more and I’m at the last page again. I noticed there’s the same problem with the Groups list too.
