Move row to latest position is impossible on reconstructed HTML/CSS structure.
Row Move functionality works incorrect
Thank you for pointing that out. It seems that the issue happens when we have overflow: auto parameter present and when the viewport height is lower than the height specified in div which is a parent to the Handsontable container. I already reported it as an issue on our GitHub, you can track its status here:
I have a quick update, we just released Handsontable v12.4.0 where the following issue is fixed. Thank you again for reporting!
