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.
