grid scroll resets after dragging

I'm currently using Flexmonster with a large dataset that renders many columns, which enables horizontal scrolling in the grid.

I've noticed that whenever I drag and drop a column to reorder it within the grid, the horizontal scroll position resets to the left. This disrupts the user experience, especially when working with wide reports, as users lose their current scroll position and need to manually scroll back to where they were.

JSFiddle reproducing the problem: https://jsfiddle.net/20wyph8k/

Steps to reproduce: 

1. Scroll horizontally to the middle or end of the table.
2. Drag a column to a new position.
3. After dropping the column, the grid scrolls back to the start (leftmost position).

I tried listening to Flexmonster events like reportchange, beforegriddraw, and aftergriddraw, but there doesn't seem to be a native method to preserve or restore the scroll state. Is there a recommended way to prevent this scroll reset or to restore the previous scroll position after a column drag action?

Thanks for your help!
