Merge pull request #9280 from weyert/bugfixes/fix-simplify-issue

[weyert]

Issue: #9261

A small fix to disable the simplify-feature of the babel's minify plugin as it stops the compilation of the storybook static build.

What I did

I have added the simplify: false-configuration to the babel.js-file

How to test

• Is this testable with Jest or Chromatic screenshots?
  No
• Does this need a new example in the kitchen sink apps?
  No
• Does this need an update to the documentation?
  I am not sure

How did my change cause a change in package-lock.json as suggested?

[shilman]

Thanks for kicking this off @weyert!! I don't see any change in package-lock.json -- looking good to me.

Since this is a core change, I want to get some feedback on it from members of our core team. @Hypnosphi @tmeasday any thoughts?

[Hypnosphi]

LGTM, here's the docs for reference https://github.com/babel/minify/tree/master/packages/babel-plugin-minify-simplify

@shilman please verify that the case from #9077 (comment) works with this change before closing #9077

@Hypnosphi @weyert did not fix #9077 so leaving that open
