Storybook with Web Components breaks if you ever install webpack and will never run again after removing it

[tsteuwer-accesso]

Describe the bug In a freshly created directory, if you npm init and then npx sb init, you can get Storybook to run. As soon as you npm i -D webpack and run npm run storybook, storybook no longer works, even if you remove webpack from your package.json and remove all node_modules and reinstall.

To Reproduce Run the following commands:

mkdir project
cd project
npm init
npx sb init
npm i -D lit-html
npm run storybook
// Choose the configuration for Web Components
// After installing, storybook runs fine
npm i -D webpack
npm run storybook
// Errors galore
vim package.json
// Remove webpack from your devDependencies
rm -rf node_modules
npm i
npm run storybook
// Errors galore and you can't ever run storybook again.

    Firefox: 90.0
  npmPackages:
    @storybook/addon-actions: ^6.3.5 => 6.3.5 
    @storybook/addon-essentials: ^6.3.5 => 6.3.5 
    @storybook/addon-links: ^6.3.5 => 6.3.5 
    @storybook/web-components: ^6.3.5 => 6.3.5 

Additional context After installing webpack and even removing it, you can no longer run npm run storybook as there will always be lots of errors.

I also tried running npx webpack config which built the file and that still results in the same errors.
