If I open https://en.wikipedia.org/wiki/James_Braid_(surgeon)?veaction=edit in Chrome 38, the viewport initially jumps to the bottom of the page (the references list). If I press a cursor key, I'm back at the top. If I reload the page, the problem is not reproducible. Cannot reproduce in Firefox either.
Chrome remembers a scroll position on the page - if a a content at the bottom of the page was viewed/edited, and Back/Forward buttons then were used, loading the same page again will display the last scroll position. So far, I could not see that anything was stored in cookies.
Note that I am able to reproduce the incorrect scroll position in Chrome in a private browser window.
