Continuing the discussion from Windows Phone IE scroll position quirks:
I’m able to reproduce the above bug report in Chrome 33 on Win 8 desktop. Post 56 is the one displayed at the top of the screen, though the top of it is scrolled off just ever so slightly. If I middle-click to open it in a new tab, the URL bar shows 56, 57 if opened in the same tab. There seems to be no difference in scroll position on same-tab vs new-tab. The first time I tried, the progress bar said 51. Now it consistently says 52.
