            Bug ID: 199658
           Summary: calling event.preventDefault() on touchforcechange
                    events prevents scrolling
           Product: WebKit
           Version: Safari 12
          Hardware: Unspecified
                OS: iOS 12
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs

Calling `event.preventDefault()` on `touchforcechange` opts out of native scrolling. It also opts out of click events.

Example: https://codesandbox.io/s/touch-events-fspff

My understanding is that this is not correct. I would think that `event.preventDefault()` on a `touchforcechange` event should only prevent the default forcechange action from occurring, and not other actions
