Inspecting a Story with Vue.js devtools

[fprijate]

I have noticed that I can inspect Story in devtools only if Story has form:

 <Story
     title="Some title"
     :layout="{ type: 'grid', width: ... }"
  > 

Regardless of whether the Story has some Variants or not (only default variant).
If so, there are 3 or more apps in devtools:

1. HistoireApp
2. MountStorySubApp
3. RenderStorySubApp ( one or more : number of variants)

Otherwise, if there is no layout prop or layout type is "single", RenderStorySubApp is/are missing.
