Associate name doesn't display when read_only set to true

[mjfaga]

I'm trying to display an association attribute to read only to ensure it can't be edited while my model is in edit mode.

My models for User and Account are defined as show here:

class User < ActiveRecord::Base
  belongs_to :account, class_name: "Account"
  ...
end

class Account < ActiveRecord::Base
  has_many :users
  ...
end

Below is the code I have in place in my rails_admin.rb initializer, where the :account is the association on my User model:

config.model User do
  configure :account do
    read_only true
  end
end

When read_only false is configued, things look as I would expect in edit mode of the User:

However, when read_only true is turned on as show in the above code snippet, I get the following while in edit mode of the User:

Any help is appreciated. Currently running Rails 4.2.5.1, Ruby 2.3.1, Rails Admin 0.8.1
