Also allows render function usage like the following:
```js
h({
'.prop': 1, // force set as property
'^attr': 'foo' // force set as attribute
})
```
@vue/runtime-dom
import { h, createApp } from '@vue/runtime-dom'
const RootComponent = {
render() {
return h('div', 'hello world')
}
}
createApp(RootComponent).mount('#app')
