Describe the bug

When there are nested fyne.Draggable Objects there is an issue which one should get the Dragged event. Most of the time this is not noticeable, especially on desktop, and was exposed on a side project that adds swipe gestures for the mobile experience.
The simplest way to quickly encounter the issue is when you have a lot of sliders inside a scroll container (see example code).
On desktop this is not an issue because we have the mouse scroll wheel and the slider on the right to scroll.
However on mobile the scrolling is implemented through the Dragged event. The slider will always take priority and the only way to scroll is if you start to scroll on a non Draggable element (the widget.Label on the left in the example code) or empty space like padding.

How to reproduce

1. Build Mobile App
2. Run the App on the mobile device
3. Try to scroll (see video)

	window.Resize(fyne.NewSize(500, 600))
	window.CenterOnScreen()
	window.SetContent(container.NewVScroll(container.NewVBox(bunchOfSliders()...)))
	window.ShowAndRun()
}

func bunchOfSliders() []fyne.CanvasObject {
	var sliders []fyne.CanvasObject
	for i := range 20 {
		sliders = append(sliders,
			container.NewBorder(nil, nil,
				widget.NewLabel(fmt.Sprintf("%d", i)), // the label
				nil,
				widget.NewSlider(0, 100)))
	}
	return sliders
