HTML reporter unusable when hosted with relative pathnames

[sannajammeh]

Describe the bug

We are deploying all our test reports to github pages in different directories.

/report-integration - shows vitest
/report-e2e - shows playwright html report

The issue we are facing is that Vitest HTML report requires pathname to empty. Eg sannajammeh.github.io/. So when deployed to sannajammeh.github.io/report-integration, the UI is a complete black screen.

I tested this during development as well. Using npx vite preview --outDir ./reports serves without a pathname successfully and the tests show. When opening an HTML server using Live Server in vscode from the testing directory, the pathname is set at <live server host>/reports. Vitest loads all JS files successfully, even the gzipped test data, yet shows a black screen with no tests.

Reproduction

I think the description suffices. There is no way to reproduce with an example without hosting to a specific pathname.
