Immutable reducer updates state with mutable objects

[ivan-nejezchleb]

If redux-router5 used as a part of immutable state it creates state updates, which contain plain JS objects.
It causes that you cant use immutable state.getIn(['route', 'params', 'paramName']) to get param's value from URL
Immutable router should handle state updates fully in immutable manner.

I will prepare PR to fix this, if it is found as a valid bug

I'm not sure I understand. Are you talking about this package or router5 package?

This package. Immutable state in redux should consist only from immutable Maps, Lists and so on. But here reducer from immutable folder sets plain JS objects into state. Creating PR, hope it will clarify this
