Ask questionsVNode.componentInstance is undefined when rendered by a functional component


2.5.17-beta.0 2.5.16

Reproduction link

Steps to reproduce

Open the console

What is expected?

An instance of MyComponent should be logged

What is actually happening?

undefined is logged

This worked in 2.5.15 It also works if you change RootComponent to be non-functional:

const content = h(MyComponent, {}, this.slots.default)

I'm guessing this was caused by 62a922e8, cloneVNode doesn't include that property.

@KaelWD Did you solve this issue? The componentInstance is also undefined when I use named slot like:

A component template

<template v-slot:body>
  <test>Hello world</test>

B component template

  <slot name="body"></slot>

B component script

export default {
  mounted () {
