Describe the bug

The coverage report (by either v8 or istanbul) does not get generated if I change the srcDir configuration in nuxt.config.js. It seems it works well if I use the default setting. You can reproduce the issue with the link I provided.

If I click on the Coverage icon button on vitest-ui web page, It shows the error text: Cannot GET /coverage/index.html.

If I run vitest with --ui and coverage.enabled option to true then the coverage report's html files should be generated in /coverage directory, but what I get is only tmp directory with coverage.json files included. It seems the .html files are not generated properly so that the output directory get empty.

I even tried to change reportsDirectory or root in vitest.config.js but nothing changes.

Additional context

Sometimes if I run vitest --ui then after the preparation is ready, the open browser should show the Vitest UI, but it shows Cannot GET /. After that if I click the URL printed on the console (UI started at http://localhost:51204/vitest/), then it goes to the UI page. Also, if I click the Coverage icon on that page, it shows the error text of Cannot GET /coverage/index.html as well.
