What happened

mergeWith working fine as per https://immutable-js.github.io/immutable-js/docs/#/mergeWith docs.
mergeDeepWith NOT working fine as per https://immutable-js.github.io/immutable-js/docs/#/mergeDeepWith.
It says like mergeDeepWith is recursive implementation of mergeWith. @leebyron Isn't it?
