cannot use default import in a component library

Steps to reproduce 🕹

Link to live example:

Steps:

1. create a basic lib component with this dummy component (with a default import):

import Paper from  '@mui/material/Paper';
import React from 'react';

export interface DummyProps {
  message: string;
}

const Dummy = ({ message }: DummyProps) => {

  return (
    <Paper>{message}</Paper>
  );
};

export default Dummy;

2. Set @mui and @emotion as a peer dependency (see config file below)

3. rollup (see config below) and publish the lib

4. Create a simple react application, with a component SuperDummy using Dummy from the lib

5. Write a unit test using SuperDummy
   => the test should fail with an error like
   React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: object.

Current behavior 😯

On one side I have a component library using react, mui and emotion as peerDep.

package.json

 "peerDependencies": {
    "@emotion/react": "^11.10.5",
    "@emotion/styled": "^11.10.5",
    "@mui/icons-material": "^5.10.15",
    "@mui/material": "^5.10.15",
    "react": "18.2.0",
    "react-dom": "18.2.0"
  }

rollup config (note the regexp for @emotion and @mui)

  external: [
    'react',
    'react-dom',
    /@emotion\/.*/,
    /@mui\/.*/,
  ],
  output: [
    {
      file: 'dist/index.cjs.min.js',
      format: 'cjs',
      sourcemap: true,
      plugins: [terser()],
    },
    {
      file: 'dist/index.esm.min.js',
      format: 'esm',
      sourcemap: true,
      plugins: [terser()],
    },
  ],
  plugins: [
    resolve({ browser: true }),
  ...
    typescript({ tsconfig: './tsconfig.json' }),
  ],
},

Lib is published with npm.

On the other side, I have a simple react application (storybook, webpack5) Nothing special on the config on this side.

When I run storybook, it works fine.
When I run the app, it works fine too.

But when I run the jest unit tests, I get this error:

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: object.

I managed to surface that the error occurs as soon as I have a default import in the component library.
Like
import Paper from '@mui/material/Paper
instead of
import { Paper } from '@mui/material';

For those basic imports, I can leave with the second import, but then, I need to use icons too (or styled from @emotion/styled)

And these imports are only default:
import Circle from '@mui/icons-material/Circle';

As a workaround, I made this wrap and now it works but it's not ideal:

import Circle from '@mui/icons-material/Circle';
import { SvgIcon } from '@mui/material';

const normalizeIcon = (Icon: typeof SvgIcon) => {
  // eslint-disable-next-line @typescript-eslint/no-unsafe-member-access
  return ((Icon as any).default ? (Icon as any).default : Icon) as typeof SvgIcon;
};

  const CircleIcon = normalizeIcon(Circle)`

Expected behavior 🤔

I would like to be able to use default imports without any error.

For instance:
import Circle from '@mui/icons-material/Circle';

Context 🔦

I will have several applications and I want to share theme and components. Hence the creation of the component library.
I want to be able to use the component library from the apps whatever the way the component library makes it's imports.
