Error with FixedColumns Rigth and visible column

Hello, I have found a problem in the library itself that I don't know how to solve it.

The problem is that when a fixed column is applied to the right, and a column before it (more to the left) is hidden, the fixed column is not kept.

To test it you can access the url: https://datatables.net/extensions/fixedcolumns/examples/initialisation/left_right_columns.html , open the command console, and run the command: $('#example').DataTable().column(1).visible(false).

Then you can check that the last column does not stay fixed correctly.

Thanks
