react/display-name false positive when using React.memo

We have a functional component that is exported with React.memo

import React from 'react'
import { string } from 'prop-types'

function Component({ world }) {
  return <div>Hello {world}</div>
}

Component.propTypes = {
  world: string,
}

export default React.memo(Component)

This triggers the react/display-name error after the update from 7.11.1

[...]/Component.jsx
  12:16  error  Component definition is missing display name  react/display-name

The exported components displayName is Memo(Component).

Without React.memo it recognizes the displayName.

export default Component

The fix in 7.12.3 works for export default React.memo(Component);, but still gives a false positive if you wrap the function directly:

import React from 'react';

const Test = React.memo(props => (
  <div>{props.children}</div>
));
export default Test;

@samsch thanks, could you file that as a new issue?
