To Reproduce
Steps to reproduce the behavior:
Make sure you have a clean local install, run `build-storybook

Expected behavior
Build should pass

Additional context

This exact build has worked fine up until approximately yesterday. The only major external change I have seen in that period is Babel releasing version 7.6, but it is difficult to find if this is failing due to that alone.

The problem is actually in the babel-plugin-minify-simplify plugin, which broke under Babel 7.6: babel/minify#967

Please try this workaround from @aaronbarker: #8744 (comment)

[afebbraro]

Thank you @shilman! npm i -D @babel/traverse@7.6.0 fixes it for me.

[brendonco]
