TypeError: Cannot redefine property after upgrading to v1.5.0

Describe the bug

Hello, I'm facing an issue when I tried to upgrade vitest version from 1.4.0 to 1.5.0. No code was changed, and now on v1.5.0 I'm getting TypeError: Cannot redefine property: error on some of my unit tests.

It works fine on v1.4.0
It dosn't work on v1.5.0, v1.5.1, v1.5.2

Reproduction

https://stackblitz.com/edit/vitejs-vite-pq9gts?file=package.json,src%2Fapp%2FAuthGuard.tsx,src%2Fapp%2FAuthGuard.test.tsx

NOTE: if you downgrade vitest to v.1.4.0 it should work fine.

This happens because react-oidc-context is now imported as an ES module which doesn't support spying. You need to add it to server.deps.inline for Vitest to patch the module:

export default defineConfig({
  test: {
    server: {
      deps: {
        inline: ['react-oidc-context']
      }
    }
  }
})
