That uses React to attach onClick, so obviously yes. I'm saying without React. You said:

> The only difference between if this were a web component vs a React component is that the consumer would not capitalize the name. Instead of `<Button appearance="primary">` they would do `<evergreen-button appearance="primary">`.

If you're not using React, you obviously can't do `onClick={...some function here...}` with Web Components, you have to use the shitty DOM APIs.

I guess I see what you're saying that web components can seem be consumed as expected from a React app. I thought we were talking about not using React at all.

But I would expect this still would not work as expected with props like `children` or other props that accept React elements. It seems like the web component would be expecting Node instances, not React elements. Since components can decide whether or not to render their children, they wouldn't be backed by Nodes yet when the web component received them. So it seems like it'd have to know whether it's dealing with React and use ReactDOM.render directly.
