What is the current behavior?
@tinymce/tinymce-react contains @storybook/storybook-deployer in the dependencies in package.json, which cascades to all configurations consuming @tinymce/tinymce-react@4.3.1

Steps to reproduce

npm install @tinymce/tinymce-react@4.3.1

What is the expected behavior?
Package forces the consuming application to only download the packages that are used during runtime when using npm i

Version: 4.3.1
PR: #478
