Not sure why this only breaks in production and not in development.

I'd say the fact it works in npm based install is actually the problem, since the two versions are in fact incompatible and we should have caught this in development rather than only after rpms are built.

npm based install has react-redux 5.1.1 while packaged version is 5.0.7. when running `npm install react-redux@5.0.7` the same error is present in development as well.

I wonder whats the difference than, as I have npm install the project (from clean env) and the bookmark form functionality does work as expected...

react-redux 5.1 seems to be compatible - https://github.com/reduxjs/react-redux/commit/1b43eaa86d89144bfe2ef72db095f69bf7944cf2#diff-4a561361865a8e6d0758088bf7cded8dR92 is the change that prevents this failure.
