According to: MONGOID-4173 nested eager loading has been merged into master, however it doesn't seem to be working correctly.

I have several models, Place, Post, Comments, User and Vote

I am making a query like: Place.includes(post: [:user, :vote, :comments]).all

However, the only thing I get back is a Mongoid::Errors::InvalidIncludes as Mongoid apparently still only supports one level of eager loading.

Am I doing something wrong, or is nested eager loading in fact not actually merged into the master branch?
