            Bug ID: 200869
           Summary: Multiple scroll events during one
                    requestAnimationFrame cycle
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: macOS 10.14
            Status: NEW
          Severity: Major
          Priority: P2
         Component: Scrolling
          Assignee: webkit-unassigned at lists.webkit.org

Safari dispatches multiple scroll events during one requestAnimationFrame "cycle". But the scroll event should be limited to the rAF.

Steps to reproduce:

1. open page:
Demo: https://jsbin.com/joculitacu/edit?console,output

2. Scroll the page

What you see:
You see multiple outputs `bug.` inside of the console.

What I expect:
No output.

To me it is not entirely clear wether this is a bug with the scroll event or the rAF.
