[Bug]: Viewport scrolling and drag'n'drop should not happen together on iOS

[sigmate]

Detailed steps on how to reproduce the bug

On iOS (and presumably Android), when using a component that relies on a Viewport (in my case a TableListBox) and if a drag'n'drop gesture is performed, both the component and its underlying viewport will react to gesture, meaning the selected item will be dragged, but the viewport will also scroll.

What is the expected behaviour?

On touch devices, I suppose there should be additional logic to handle gestures depending on wether some items are selected or not and where the gesture originates. Like:

Drag gesture starts
  If gesture start point is not inside an already selected item then
    Scroll viewport
  Else
    Begin item dragging
