            Bug ID: 191017
           Summary: Provide a way for scrollToTop to apply to an element
                    other than the body
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: iPhone / iPad
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
          Assignee: webkit-unassigned at lists.webkit.org

Normally, a tap on the status bar causes a page to scroll to the top. This is consistent with UIScrollView behavior throughout iOS.

An native app can determine which scroll view scrolls on scroll-to-top gesture as controlled by scrollsToTop:
https://developer.apple.com/documentation/uikit/uiscrollview/1619421-scrollstotop

In WebKit, only the body can scroll to top. Sometimes the main content of the page is an other scrolling element. For example photos.google.com when signed in does not scroll the body. As a result, double tapping the status bar does not scroll the page.

It would be helpful to have a way to receive this event and handle it with JS or to specify which element should scroll instead of body.
