                    history navigation
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: History
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: majidvp at chromium.org

Currently there is no reliable and cross-browser solution for developers to opt out the automatic scroll restoration behavior or control any of its aspects.
The automatic restoration works well for document style web sites but it is often not appropriate for single-page web applications where they are
re-constructing the page content onpopstate every time and often asynchronously or need to control the visual transition between states. 
Here is more the problem background and existing workarounds: http://majido.github.io/scroll-restoration-proposal/


We in blink team have proposed a solution to this issue on WHATWG and there is some consensus (with spec editors and Mozilla experts) around a simple API based on a new attribute added to the history object.
I would like to know if Webkit has any feedback on this solution and API and help make the consensus more inclusive if possible.
