[gatsby-plugin-mdx] <MDXRenderer /> components prop does not work

[hjfitz]

Description

When passing components to <MDXRenderer /> , those components are ignored

Steps to reproduce

I'm using an exported pageQuery to pull in mdx:

  query PageQuery($id: String) {
    mdx(id: { eq: $id }) {
      id
      body
      frontmatter {
        title
    date
      }
    }
  }

and trying to render this with a wrapper function:

import React from 'react'
import {MDXRenderer} from 'gatsby-plugin-mdx'

const P = (props) => <p className="" {...props} />

const H1 = (props) => <h1 {...props} className="text-4xl" />

const components = {
  p: P,
  h1: H1,
}

const wrapper = (children) => <MDXRenderer components={components}>{children}</MDXRenderer>

export default wrapper

Expected result

What should happen?

My <h1 /> should have the class text-4xl

Actual result

What happened.

It doesn't.
