Plugin `transformIndexHtml` called with a `*.html` id that's `import`ed and not an entrypoint during `vite build`.

[miguel-leon]

Describe the bug

I expect transformIndexHtml to be called only with entrypoints .html files, and it is like so during vite dev. But during vite build, other .html that is not an entrypoint.

Reproduction

https://stackblitz.com/edit/vitejs-vite-bqwee1at?file=vite.config.js

Steps to reproduce

Run npm install followed by npm run dev.

Only the entrypoint index.html printed to the console.

Run npm run build.

Non-entrypoints .html printed to the console.

• 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.
• Make sure this is a Vite issue and not a framework-specific issue. For example, if it's a Vue SFC related bug, it should likely be reported to vuejs/core instead.
• 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.

Not sure if it's related to passing the file by transformIndexHtml, but there's also the derived issue that, the result from load is attempted to be parsed as html, and that sometimes causes a parse5 error.

I updated the repro to produce such error during build.

PS: What is the purpose of that parsing?
