Created attachment 136958 [details] popstate scroll restore test case If you scroll to the bottom of a long page and use pushstate to navigate forward, going back will restore the wrong position. The restored positioned will be clipped to the max height of the previous page rather than fully scrolling to the bottom. It seems that if you force a synchronous relayout/reflow within the popstate handler, the position will be restored correctly. The bug affects Safari, Chrome, and Firefox. But the hack doesn't appear to fix it in Firefox. Strangely it all works fine if you use the back/forward touch gestures in Safari. See the attached test case. (Note that uncommenting the relayout line fixes the issue) Possibly related issues: * https://bugs.webkit.org/show_bug.cgi?id=33931
