Steps to reproduce

<script setup>
import { h, ref, onMounted, defineComponent, nextTick } from 'vue'

const Test = defineComponent({
  setup() {
    const flag = ref(true);
    const elementRef = ref();

    onMounted(async () => {
      flag.value = false;
      await nextTick();
      console.log(elementRef.value);
    });

    return () => {
      return [
        flag.value && h('div', { ref: elementRef }, 'div1'),
        !flag.value && h('div', {}, 'div2'),
      ];
    };
  },
});
</script>

<template>
  <Test />
</template>
