Resolving nested async functional components is broken

Steps to reproduce

As already quickly mentioned in here 03c13de nested functional components are broken since 2.6.8
1.) I have 2 functional components in the repro (Logo.vue / LogoWrapper.vue)
2.) The components are registered globally as async components (doesn't really make sense in this case.. but you should get the point :-)). Check components/_globals.js
3.) Using one of the component in the other (Logo inside LogoWrapper) breaks with the errormessage "Cannot read property '$on' of null" - this was working prior to 2.6.8

What is expected?

Components are renderer, no error message.

What is actually happening?

TypeError
Cannot read property '$on' of null

I can't reproduce this locally. This may have something to do with functional template compilation? Can you manage to provide a repro without Nuxt or any build system involved?

After looked source code, I guess this can only happen with SSR, I will try make a test case for this.

yes, as mentioned by @dejour the bug only happens with SSR. Should I still add another repro without nuxt?
