Type-only boolean props do not work in production mode

Reproduction link

Repo: github.com
Example: https://confident-agnesi-a384b9.netlify.app/

Steps to reproduce

1. Define a component with a boolean prop using the type-only defineProps syntax.

defineProps<{ checked?: boolean }>()

2. Render the component using a prop with no value

<Child checked />

3. Build for production

What is expected?

The child component should be rendered with the prop defined as true. The correct behavior occurs in development mode.

What is actually happening?

The prop is defined as an empty string and interpreted as false

---

It looks like the minified code is not matching what is described in the documentation

In prod mode, the compiler will generate the array format declaration to reduce bundle size (the props here will be compiled into ['foo', 'bar'])

But looking at the dist files, I see props:{checked:null}

Closing, looks like a duplicate of #4783 and I expect will be fixed with the next patch release.
