Duplicate export 'default' in linaria v5

[eKazim]

Environment

• Linaria version: 5.0.3
• Bundler (+ version): Webpack 5, webpack5-loader 5.0.4
• Node.js version: 18.17.1
• OS: Win 10

Description

After upgrade linaria version from v4 to v5 i getting error from loader:

ERROR in ../components/src/index.ts 53:92
Module parse failed: Duplicate export 'default' (53:92)
File was processed with these loaders:
 * ../../node_modules/babel-loader/lib/index.js
 * ../../node_modules/@linaria/webpack5-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.
| export { ModalsProvider, ModalsProviderProps, default, useModalState } from "./ModalsProvider/index.js";
> export { ThemeProvider, useTheme, default } from "./theme/index.js";
| export { useSubMenu, SubmenuPositions } from './utils/useSubMenu.js';
...

Source code of index.ts has only reexports:

export * from './ModalsProvider/index.js';
export * from './theme/index.js';

export { useSubMenu, SubmenuPositions } from './utils/useSubMenu.js';

Re-exported modules has other named exports and default. Wildcard exports should works fine in this case and it parsed correctly in previous version of linaria/webpack5-loader.

Reproducible Demo

Simple example:

webpack.config.js

...
use: [
	'babel-loader',
	{
		loader: '@linaria/webpack5-loader',
		options: { sourceMap: devMode }
	},
],

linaria.config.cjs

module.exports = {
  babelOptions: {
    presets: ['@babel/preset-typescript', '@babel/preset-react'],
  },
};

src/moduleA.ts

export const namedA = 'namedA';

const componentA = 'componentA';
export default componentA;

src/moduleB.ts

export const namedB = 'namedB';

const componentB = 'componentB';
export default componentB;

src/index.ts

export * from './moduleA.js';
export * from './moduleB.js';

I am seeing this in v6 as well (with WyW). it feels like the loader is expanding * as Namespace imports and emitting duplicate names. this is blocking me from using v6 😢
