Copy JSX does not work with forward ref

This will output something like this:

```js
<[object Object]
  loading
  size="large"
>
  PrimaryButton
</[object Object]>
```

This is likely and issue with react component to jsx string. See advanced usage with forward ref to try and solve the problem: https://reactjs.org/docs/forwarding-refs.html#displaying-a-custom-name-in-devtools
