Reproduction

https://stackblitz.com/edit/github-sguz8t

Describe the bug

After build, props of elements in a DevOnly's fallback slot are emptied. For example, after executing npm run generate on the reproduction and taking a look at .output/public/index.html, you can see class="red" turned into class="".

Additional context

This issue was not present in Nuxt 3.6, so I think it might be a recent regression.
