My mdx code:

---
name: Button
---

import { Playground } from 'docz'
import { Button } from './button'

# Button

## Basic usage

<Playground>
  <Button
    label='Click me'
  />
</Playground>

More Information: I already see this issue: https://github.com/pedronauck/docz/issues/540 And I already install the docz-theme-default and still crash

EDIT: I did this example app to simulate the problem, take a look: https://github.com/rodrigowpl/rn-docz-play

Expected behavior

Render without crashing

This works for me -

  "devDependencies": {
    "@emotion/core": "^10.0.6",
    "docz": "^0.13.7",
    "docz-theme-default": "^0.13.7",
    "emotion-theming": "^10.0.6",
  },
