Bug report

When a user clicks on a locked column header (for example for sorting), the focus unexpectedly shifts to the first unlocked column instead of remaining on the clicked header.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/bZUXgWQT.
2. Click on the ID or Name header.

Current behavior

The visual/keyboard focus immediately moves to the first unlocked column. If the user clicks the second locked column, the focus shifts to the second unlocked column.

Expected/desired behavior

Clicking on a locked column should retain focus on that column, not move to another grid column.

Regression

The issue is a regression starting with 2022.3.913 version

1. Open the Keyboard Navigation demo - https://demos.telerik.com/kendo-ui/colorpicker/keyboard-navigation
2. Open either of the ColorPickers
3. Press tab until you focus the last focusable item in the popup

Current behavior

Pressing tab again moves the focus out of the popup

With Kendo version 2025.2.520 the filterInput text has been set and the current value is 'Filter'. However, there is no built-in option in the API that provides the possibility to change the text. As the text is not part of the messages, it can not be localized in case another language is used.

Dojo - https://dojo.telerik.com/zidaocyO

Add the filter input text to the messages so localization and customizing the text are possible.
