Forward-Back-Navigation with infinite scrolling
Not sure this can be fixed (i.e) it is a feature not a bug.

After scrolling 'lets say more than 1 page' with infinite scroll. I click on a select tweet (neet?) or image. Now it opens (in the same Tab). But now press back and you are now located at a different scroll position. Tested with Bromite.

Not sure how other sites keep it.
