Column reorder won't work for the first time when the container is horizontally scrolled.
I've attached a sample file of html to reproduce the issue.
And also a screenshot with directions.
The defect reproduces when we click on the horizontal scroll bar empty space not drag the scroll bar, we'll observe that reorder doesn't happen first time. And after that reorder happens as usual.
