Bug report

Spreadsheet validation on datatype=list, values in the dropdown are parsed to numbers. Numeric strings are automatically formatted by removing the heading zero.

Reproduction of the problem

Dojo: https://dojo.telerik.com/eOOvKJxL

                  validation: {
                      dataType: "list",
                      showButton: true,
                      comparerType: "list",
                      from: "{ \"001\", \"002\", \"Baz item 3\" }",
                      allowNulls: true,
                      type: "reject"
                    } 

The bug is a regression, formatting is different with a 2017 version: https://dojo.telerik.com/sCvgBzBa/5
