Bug report

When the scrollable option of the Grid is set to "virtual: 'columns'", the reordering of the columns cannot be performed while dragging over the field headers.

Regression introduced with 2022.3.913

Reproduction of the problem

1. Open the Dojo example - https://dojo.telerik.com/AMeHorIC/3
2. Try to reorder the columns while dragging over the field headers.

Current behavior

The columns cannot be reordered from the field headers. Instead, the field headers are flickering.
Screen recording - https://screenpal.com/watch/c0jrQ2Vpr8e
If the reordering is performed below the headers, it works properly.

Expected/desired behavior

Should be able to reorder the columns from the field headers without flickering.
