Vitest browser mode tests not working when running in a sub directory

[nicojs]

Describe the bug

Similar to #3363, vitest's browser mode doesn't work when run from a subdirectory.

For example, this directory tree:

.
├── package-lock.json
├── package.json
└── test-resources
    └── browser-project
        ├── node_modules
        ├── package.json
        ├── src
        │   ├── heading.component.spec.ts
        │   └── heading.component.ts
        └── vitest.config.js

And you cd into test-resources/browser-project and run npx vitest, you get this error (or similar):

TypeError: Failed to fetch dynamically imported module: http://localhost:5173/@id/vitest/utils

Reproduction

See this reproduction repo.

1. Run npm i
2. cd into test-resources/browser-project
3. Run npx vitest

browser-project.zip

This error should be fixed in the next beta release (already merged), it's not about a subdirectory

Thanks @sheremet-va. I've noticed beta5 got released yesterday and tried it on this example. It seems to work now 🎉

However, I now notice another issue when implementing browser mode inside StrykerJS's mono repo. The browser opens and seems to redirect infinitely; see the animated gif below.

You can find the source code for this example here: https://github.com/stryker-mutator/stryker-js/tree/feat/vitest-browser-mode/packages/vitest-runner/testResources/browser-project

I've found the cause for this last error and created a new issue: #4570. Closing this one
