If you want to use a custom component element as a child of the Tooltip, ensure you forward the ref to the DOM node:

```
import React, { forwardRef } from 'react';
import { Tooltip } from '@bigbinary/neetoui';

const ThisWontWork = () => {
  return <button>Reference</button>;
}

const ThisWillWork = forwardRef((props, ref) => {
  return <button ref={ref}>Reference</button>;
});

function App() {
  return (
    <Tooltip content="Tooltip">
      <ThisWillWork />
    </Tooltip>
  );
}
```
