Describe the bug

When executing the tests, each test fails because of TypeError: __vi_esm_0__.default is not a function.
After reducing it to the minimal reproducible example, I could isolate that the issue is the package pino.

You can find "working" tests here src/browser/working.spec.ts

The mocking does not work, but this is besides this bug

But the same code that uses pino is not able to load it: src/browser/logger.spec.ts

Reproduction

1. git clone https://github.com/NicoVogel/logger-wrapper
2. git checkout bug/vitest-browser-vi-esm-0-default-not-a-function
3. (optional) reopen in dev container
4. pnpm install
5. cd packages/logger
6. pnpm exec vitest -c vitest.browser.ts
