Steps to reproduce

Steps

0. git checkout demo1

1. pnpm i

2. open main.tsx

3. there is a error hint at line 19

   src/main.tsx:19:33 - error TS2322: Type '() => number' is not assignable to type 'void'.
   
   19 const app = createApp(<div><App onClick={() => 1} /></div>)
   

4. comment out type Props(lines 7 ~ 9), uncomment interface Props(lines 4 ~ 6), then it works without errors.

What is expected?

type Props works without type errors in code below

type Props = {
  onClick: () => void
}

const App = defineComponent<Props>({
  setup() {
    return () => (
      <div>App</div>
    )
  }
})

const app = createApp(<div><App onClick={() => 1} /></div>)
app.mount('#app')

What is actually happening?

type Props does not work as expected
