Attributes: { tabIndex: 10 } for form elements other than { view: "text" }?

Hi,

In a Webix form, is it possible to add attributes: { tabindex: 100 } to a form element other than { view: “text”} ???

Like {view: “checkbox”, attributes: { tabindex: 100} } or {view: “button”, attributes: { tabindex: 100 } } for example?

I only seem to be able to get this to work for { view: “text”, attributes: { tabindex: 100 } } …
