Summary calling event.preventDefault() on touchforcechange events prevents scrolling

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

I do not have access to an old device right now, but I think this might be a recent change
