it's still nothing after render

const render = (vnode, container, isSVG) => { if (vnode == null) { if (container._vnode) { unmount(container._vnode, null, null, true); } } else { patch(container._vnode || null, vnode, container, null, null, null, isSVG); }

after search in code, I found that it alwasy pass null as parentComopnent to render
and this will ignore setRef function

   if (ref != null && parentComponent) {
            setRef(ref, n1 && n1.ref, parentSuspense, n2 || n1, !n2);
        }

I think you can use this:

playground

<script setup>
import { ref,onMounted ,h,render} from 'vue'
  
const div = ref(null)
const a = ref(null)
const b=ref(false)
onMounted(() => { 
  const test = h('div', { ref: a }, 'test')
  render(test, div.value)
  console.log(test.el) // this may be same as ref

  b.value = a.value == null
})
const msg = ref('Hello World')


</script>

<template>
  <h1>{{ msg }}</h1>
  <input v-model="msg">
  <div ref="div" ></div>{{b}}
</template>

yes, it's the same as setRef
