Description

@mgnjatovic-kushim Try setting the option forceFallback:true. HTML native DnD has it's own autoscroll method that doesn't work the same as the implemented autoscroll.

Contributor guide

Research direction
Investigate the conflict between CSS 'scroll behavior: smooth' and Sortable's fallback autoscroll. Check if 'forceFallback:true' correctly handles smooth scrolling by examining the autoscroll implementation and testing with and without the CSS property.
