https://stackblitz.com/edit/react-s8ugrr-dvxqcf?file=app/main.jsx

When you click in the TextArea in the above StackBlitz, React throws a warning in the console:

Warning: Received `true` for a non-boolean attribute `visited`.
 
If you want to write it to the DOM, pass a string instead: visited="true" or visited={value.toString()}.

Hello, Kyle,

This is a known warning and I have added your report to the issue:

https://github.com/telerik/kendo-react/issues/791

As this is just a warning for an attribute, the component should be working as expected and the warnings are only shown in develop mode, not in production.
