Angular: The background color switch does not work dynamically in docs tabs.

[ThibaudAV]

Describe the bug

The background color switch does not work dynamically in docs tabs.
Apparently only on Angular

To Reproduce
Steps to reproduce the behavior:

1. Go to 'https://next--storybookjs.netlify.app/angular-cli/?path=/story/welcome--to-storybook'
2. Click on 'Docs' tab
3. Click on
   
   And change color
4. See error
   The background color dose not change.
   I have the impression that it is decorators who are not called 🤔

Expected behavior
The background must change as in canvas

This issue seems to have corrected the 🐛 . but only for the React part ?? :note-sure:
#12305

@ThibaudAV I think this might be an issue for stories that run in iframes (angular), but has been fixed for inline stories (most other popular frameworks). @yannbf can you confirm?

[ThibaudAV]

@shilman you're right it seems to be related to iframe

So I'm going to propose PR to add "inline" stories support for addon docs with angular.
This is my christmas present 🎁 xD
