dispatchMouseEvent.type mouseWheel support

See original GitHub issue

I think we can implement a mouse.wheel function, which would call dispatchMouseEvent with type mouseWheel

  async wheel(options = {}) {
    await this._client.send('Input.dispatchMouseEvent', {
      type: 'mouseWheel',
      deltaX: options.deltaX,
      deltaY: options.deltaY
    });
  }

It isn’t enough for us to check the body scroll position. Internal elements could scroll. Scrolls could be captured. They could land in shadow dom or iframes. Trying to figure out when a scroll has finished from JavaScript is going to require many layers of hacks, if it is doable at all.

There have been some patches related to this landing in Chromium. I need to find some cycles to move dispatchMouseEvent to a better code path for wheel events, but right now it’s unfortunately not a high priority for me.
