Template Ref watcher is not triggered with flush: post option in Vue 2.7.

Version

2.7.6

Reproduction link

codesandbox.io

Steps to reproduce

Open the CodeSandbox and watch the console output.
There seems to be a problem when Template Ref watcher components are nested.

What is expected?

There should be a log entry for App.vue.

What is actually happening?

There's no log entry because the watcher is not triggered.

This works in Vue 3.

Yeah, had the same issues while used useResizeObserver from @vueuse/core. It was working fine on 2.6 and stopped working on 2.7.
