Version

2.6.11

Reproduction link

https://codepen.io/PatriciusSanctus/pen/PowdQpq

Steps to reproduce

Vue.component('func-parent', {
  functional: true,
  provide: () => ({ foo: 'bar' }) // || { foo: 'bar' }
})
Vue.component('func-child', {
  functional: true,
  inject: ['foo']
})

What is expected?

i want use injection in render() function

What is actually happening?

[Vue warn]: Injection "foo" not found

---

without DOM i can't send parent`s props to child for control child behavior (simple example: "grid-row -> grid-col")
