Describe the regression

Starting 7.1.8, vite-rolldown started to remove comments even when minify: false is set. In my case, I have comments like these in my library code, and I need to ship my library with them.

/* @vite-ignore */
/* webpackIgnore: true */

in 7.1.7, comments were preserved when minify: false

Reproduction

https://stackblitz.com/edit/vitejs-rolldown-vite-jqpqhd91?file=vite.config.js

Expected Behavior

When minify: false comments are not removed

Actual Behavior

Comments are removed

Steps to Reproduce

1. run build in 7.1.8 and see dist/main.js - no comments
2. run build in 7.1.7 and see dist/main.js - comments preserved
