Bug report

In a Grid where custom filterable ui is configured, and the filterable.extra is set to false, the data is not filtered correctly.

Regression introduced with 2025.1.211

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/ARMkquiy/12
2. Filter the Start Period column by choosing "NO" in the dropdownlist

Current behavior

No data is shown in the Grid, as it appears that the logic for the filterable.extra is not applied

Expected/desired behavior

The data should be correctly filtered with the above configuration.

Environment

• Kendo UI version: 2025.2.520
