• The touch event in chrome/webkit is invalid in edge. Edge continues the MSPointer event of IE10;

• However, touch events in edge are turned off by default, see the picture below;
  

• The "Use two fingers to drag to scroll operation" of the surface trackpad does not trigger MSPointer events either on IE11 or edge.

Above, two questions:

1. Is there any way to bypass the about:flags setting of edge and use touch/MSPointer to do the event?

2. Looking for the event caused by "Use two fingers to drag for scrolling operation"? (Premise: The page layout content cannot be scrolled and cannot be obtained through the scroll event)

I hope someone can give me an answer, thank you very much!
