Drag&Drop with scrolling not working on tablet in scheduler

On a tablet (both iPad & android), when you drag an event to the bottom or top of the scheduler, the scheduler does not scroll up or down. This is working as expected on desktop but not on mobile.

The scrolling behavior can be found by the following link: https://javascript.daypilot.org/demo/scheduler/scrolling.html
