can not test Dialog component.

[OlegRyzhkov]

I was trying to test my wrapper for Dialog component and I got a big stacktrace

• [?] The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

test failed and shows irrelevant stacktrace (for me)

Expected Behavior 🤔

test is passed correctly and creates snapshot file.

Steps to Reproduce 🕹

1. create react app.
2. install material ui.
3. replace file App.test.js with this:

import React from 'react';
import renderer from 'react-test-renderer';
import { Dialog, DialogActions, DialogContent, DialogTitle } from '@material-ui/core'

test('Sidebar', () => {
  const component = renderer.create(
    <Dialog
      open
      onClose={() => {}}
    >
      <DialogTitle>qweqw</DialogTitle>
      <DialogContent>qweqweqwe</DialogContent>
      <DialogActions>
      </DialogActions>
    </Dialog>
  );
  let tree = component.toJSON();
  expect(tree).toMatchSnapshot();
});

4. run npm test
   https://codesandbox.io/s/kind-hugle-r14zn

I see a different stacktrace in codesandbox fr some reason. am I doing something wrong?
