@sdgandhi: sorry, I lost sight of this in my inbox. Do you have a suggestion how I can test this? I tested a few contexts/applications, and everywhere a contextual menu showed up, which resulted in a behavior that didn’t allow for testing dragging.

@BlueM I think this could be tested on an ios simulator which should result in a scrolling action. It may also be able to be tested by starting a left click drag action first then right click drag which ideally would also result in scrolling.
