            Bug ID: 191218
           Summary: Touch event not firing while scrolling is in motion
           Product: WebKit
           Version: Safari 12
          Hardware: iPhone / iPad
                OS: iOS 12
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Event Handling
          Assignee: webkit-unassigned at lists.webkit.org

When user scrolls and in the deceleration phase of the inertial scrolling, user touch the screen will make the scrolling stop but no "touch" event is fired. I'd like to detect where the user touch to stop the scrolling but I can't because there's no event firing. Safari and Chrome on iphone have this issue while Android doesn't.
I've created a CodePen for testing.
