Describe the bug

Updating vitest to version 0.25.7 breaks unit tests for Svelte-based website.

Reproduction

• Clone https://github.com/DirkRaeder-KDO/vitest-0.25.7-breaking-tests
• Install the dependencies using your pnpm, yarn or npm.
• Run the unit test (pnpm test:unit, yarn test:unit, npm run test:unit)
• Update vitest from 0.25.6 to 0.25.7
• Run the test again

Expected behavior: In both cases, the unit test succeeds.

Actual behavior: The unit tests succeeds only with vitest@0.25.6. It fails with vitest@0.25.7.

Later versions of Vitest: The test fails with 0.28.4 (latest) as well.

Notable changes from 0.25.6 to 0.25.7:

• Vite has been upgraded from 3 to 4.
• Rollup is a dependency of Vite and has been upgraded from 2 to 3
