Back button returns me to top of feed.

[tgm-git]

What happened

First I scroll down and press the more button, then I scroll some more. After a while I click on a post and press the back button. I am returned to the top of the feed instead of the page I was at when I opened the comment

What I expected

When I have scrolled down a page or more I expect to be returned to the last page I was looking at on the feed when pressing the back button.
