How to reproduce:

• Make a change in the JSDoc of addEntities to be found inpackages/core-data/src/actions.js
• Make a change in the JSDoc of canUser to be found inpackages/core-data/src/selectors.js
• Execute npm run docs:build.

Notice how packages/core-data/README.md only reflects the changes in the selectors.js file, while docs/designers-developers/developers/data/data-core.md contains both changes.
