`@vitest/web-worker` error when using browser environment

Describe the bug

I'm trying to get test coverage output with istanbul but I've found out vitest can't see codes executed in web workers (per #2911). So I figured I could wrap my worker with @vitest/web-worker and execute it in main thread. However, since that worker executes WebAssembly I want to keep using browser environment.

Now, in theory I don't see any problem with this approach but I'm getting a dynamic import error.

TypeError: Failed to fetch dynamically imported module: http://localhost:5173/home/foo/workspace/bar/node_modules/@vitest/web-worker/dist/index.js?v=1704701752071

This could be just a configuration error on my side, maybe there is a way to bundle this worker wrapper in browser environment but that didn't shine any ideas to my mind.

Reproduction

If the problem is not obvious I'll create a reproduction project

• Follow our Code of Conduct
• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.
• Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.
• The provided reproduction is a minimal reproducible example of the bug.

Start by reducing the browser-environment setup to a minimal reproduction using @vitest/web-worker and a WebAssembly-executing worker. Then trace the dynamic import of @vitest/web-worker from the browser entry point; done means the worker wrapper loads and executes successfully while browser testing and coverage remain usable.
