Class not passed when component has a comment (production build)

[guillenotfound]

Describe the bug

Classes not passed down components from vue-router when component has a comment, only happens on production build.

Reproduction

Here's a demo repository with the issue, if you run vite it will work, but if you build and use a server like caddy --root dist --listen :3001 you'll notice that no class are injected when rendering home or sidebar components.

Second.vue is the only component without a comment inside the template, during development all classes defined for router-link are passed down to the components but those classes are missing when building for production as shown in the image below:

System Info

• required vite version: rc4
• required Operating System: mac os x
• required Node version: 12.18.4
