Disable slide drag move on mobile (not transition)

Is there any way to disable finger drag moving a slide, on mobile devices? I've disabled swipe transition (Prev, Next) in the 'Slide Navigation and Gestures' but this doesn't seem to disable the slide moving, when dragged. Am I missing some setting here?

See attached clip for example. Captured in Chrome using developer tools (device toolbar).

Even a JS hack would be welcome.
