Bug report
The first unlocked column cannot be dropped into the next locked column.
Regression since 2021.3.1207
Reproduction of the problem
- Go to the Frozen columns demo
- Start drag from the ShipCountry (the first unlocked column) column header.
- Drop to the right of the ShipName (locked column) column header.

Expected/desired behavior
ShipCountry should become a locked column and move after the ShipName like how it worked in version 2021.3.1109
