Reproduction

https://stackblitz.com/edit/github-wzqq2xfw?file=app/app.vue

Describe the bug

I noticed that after building Nuxt, the % unit in CSS gets stripped from all values that are 0, which causes the linear() timing function to break, because it always expects a percentage on the right side.

.example {
  transition-timing-function: linear(0 0%, 1 100%);
}

Steps to reproduce

1. run pnpm build
2. run pnpm preview
3. inspect the CSS of the Example div

Additional context

Might not be a Nuxt bug, but I wasn't able to reproduce it in plain Vue: https://stackblitz.com/edit/vitejs-vite-u8bwhrqx?file=src/App.vue&terminal=dev
