Describe the bug

Preface: thank you for all of your hard work; Browser Mode with the preview provider is the reason I strongly favor vitest for my project. I need the speed of Jest, the runtime inspectability of Cypress or Playwright, and the clean architectural simplicity of vite -- and you are poised to deliver! ❤️

When I write a trivial test for a trivial component and try to run vitest, nothing works. It seems something is going very wrong with module paths on disk and/or contents, as represented in the bundled code which makes it into the browser. Perhaps the test server is being influenced by a bad configuration choice in one of my vite/tsconfig files?

The first telltale happens when I open the runner:

$ npx vitest

 DEV  v2.0.0-beta.12 <basedir>
      Browser runner started at http://localhost:5173/

Sourcemap for "<basedir>/node_modules/@vitest/browser/dist/client/__vitest_browser__/client-Dz5Ebwug.js" points to missing source files
Sourcemap for "<basedir>/node_modules/vitest/dist/runners.js" points to missing source files
Sourcemap for "<basedir>/node_modules/vitest/dist/vendor/setup-common.CWnv_2-5.js" points to missing source files
Sourcemap for "<basedir>/node_modules/@vitest/snapshot/dist/index.js" points to missing source files

My favored browser (Chrome) opens and happily shows the vitest UI, but my test is stuck in "pending" forever:

Opening the browser console reveals more errors:

Uncaught SyntaxError: The requested module '/node_modules/@vitest/runner/node_modules/pretty-format/build/index.js?v=3e2658e0' does not provide an export named 'format' (at chunk-display.js:1:10)

Uncaught TypeError: __vitest_browser_runner__.runTests is not a function
    at <basedir>/src/atoms/__tests__/button.test.tsx:86:27

Reproduction

I've created a public repository with a minimal reproduction.

Just clone, npm install, and npx vitest.
