When you add a KendoReact Editor component as a child of a Form component, the toolbar buttons submit the form. This is actually a defect in my opinion, so I filed a bug on it. The buttons are rendered as html button elements without a type attribute, which means they default to submit buttons. I would still like to use this Editor, so until that is fixed is there currently a way of overriding how toolbar buttons are rendered?
Here's the bug I filed: https://github.com/telerik/kendo-react/issues/219
