Grid CaseSensitiveFiltering feature does not work for multiple columns

[eyupyusein]

Bug report

The CaseSensitiveFiltering property should control whether the filtering respects the lower and upper case filtering of the values. It stops to do that for applied first filter when the Grid is filtered by a second column.

Reproduction of the problem

Run a standard Core Grid project and apply this property:

                        .DataSource(dataSource => dataSource
                            .Ajax()
                            .CaseSensitiveFiltering()
                            .PageSize(20)
                            .Read(read => read.Action("Orders_Read", "Grid"))
                         )

Filter with Shipname 3 and no records will be shown as expected:

Now filter with ShipCity 3 and a row appears although the previous filter should still be applied:

Expected/desired behavior

The first filter applied should be respected with CaseSensitiveFiltering and there should be 0 records returned.
