Describe the bug

Bug

A comment inside a dynamic import() with a template literal prevents Vite 8's dynamicImportVarsPlugin from transforming it into a static glob map.

// BROKEN — import is left untransformed, matching files are not bundled
const strings = await import(/* strings */ `./translations/${locale}/strings.json`);

// WORKS — transformed into a static Object.assign map with all matching files
const strings = await import(`./translations/${locale}/strings.json`);

These comments are harmless in Vite 7 (Rollup and Rolldown) but break dynamic import resolution in Vite 8 (Rolldown).

Expected behavior

Both forms should produce identical output.

Reproduce

npm install
npm run build

Inspect dist/assets/index-*.js:

• With comment: the import() passes through untransformed — no translation chunks are emitted.
• Without comment: dynamicImportVarsPlugin produces the expected static map and separate chunks for each translation file.

Steps to reproduce

Run npm install followed by npm run build

To see it working correctly remove the comment inside the import at main.js
