Referring to the column drag drop on Detailslist demo available on https://developer.microsoft.com/en-us/fabric#/components/detailslist/draganddrop
Things are working fine on the demo, but the column header text can be seen moved by 1px after a certain amount of time in related sites (mentioned below). Currently things are working in the demo because there's a CSS hack for that. We need to improve the solution for fixing this issue.
Column header text is moving by 1px up after certain timeout.
Column header text should remain fixed after the drag drop is finished completely.
Are you willing to submit a PR to fix? Yes
