Angular: StoryStoreV7 breaks components with decorators

[adrilolo9]

Describe the bug
After enabling the storyStoreV7 feature, stories that use decorators break, leaving an undefined message replacing the component.

To Reproduce

• Enable storyStoreV7
• Add a decorator to a story, example: decorators: [componentWrapperDecorator((story) => <div style="margin: 3em">${story}</div>)]
• Make sure the story does NOT have any template, so it uses the component.
  

Additional context
The story parameter of the decorator becomes undefined when turning storyStoreV7 on, so you are left with an undefined message.

Hi @adrilolo9

Please create a reproduction by running npx sb@next repro and following the instructions. Read our documentation to learn more about creating reproductions. Paste your repository and deployed reproduction here. We prioritize issues with reproductions over those without.

Also, what framework/renderer is this? Your story function looks like maybe it is using Angular but the decorator looks like React?

Our company also getting the same issue.

turning storyStoryV7 on in an angular 6.5.12 project, with a decorator such as

componentWrapperDecorator(
      story => `<div style="margin: 5em; background-color: #ffffff; display: inline-block">${story}</div>`
)

results in story being undefined.

Turns out this is a duplicate of #17330 and there is a fix is here: 23a3438

Because its not in the 6.X line, the best solution is to use patch-package to patch this.

@tmeasday This can probably be closed as a duplicate

OK, thanks @DavidDudson
