Desktop Pickers in v5.0.0-alpha25 doesn't show

[Chojecki]

Hi, when I'm trying to use some of desktop pickers like DatePicker or TimePicker, I can't open pickers. When I'm clicking on textfield or icon, the div with role dialog appears for a second in DOM and disappear instantly.

• 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 😯

Desktop Pickers not showing.

Steps to Reproduce 🕹

Steps:

1. Crate react app by CRA
2. Add material ui 5.0.0-alpha25
3. Add material ui lab@next
4. Add date-fns
5. Copy any desktop picker from documentation example
   like:

import * as React from "react";
import TextField from "@material-ui/core/TextField";
import AdapterDateFns from "@material-ui/lab/AdapterDateFns";
import LocalizationProvider from "@material-ui/lab/LocalizationProvider";

import { DesktopTimePicker } from "@material-ui/lab";

export default function AppDatePicker() {
  const [value, setValue] = React.useState<Date | null>(null);

  return (
    <LocalizationProvider dateAdapter={AdapterDateFns}>
      <DesktopTimePicker
        label="For desktop"
        value={value}
        onChange={(newValue) => {
          setValue(newValue);
        }}
        renderInput={(params) => <TextField {...params} margin="normal" />}
      />
    </LocalizationProvider>
  );
}

6. Try to open picker

Mobile pickers works ok.
