What happened?

When running browser tests and importing CJS modules through Vite, it sometimes happen that we get the following error:

Error:  Test failed due to following error(s):
  - pr-eact.test.tsx: Failed to fetch dynamically imported module: http://localhost:39259/node_modules/.vite/deps/@testing-library_preact.js?v=60c2fbb0: TypeError: Failed to fetch dynamically imported module: http://localhost:39259/node_modules/.vite/deps/@testing-library_preact.js?v=60c2fbb0

Usually it resolves when reloading the page which is why we look for this error in the browser runner. However we have experienced in our build that sometimes even reloading doesn't resolve the issue.

What is your expected behavior?

The CJS transformation should work flawlessly, the error should not appear.

How to reproduce the bug.

Unskip this test and run it in CI.
