Research direction

Reproduce the behavior using the custom /lib/my_module.rb, /config/initializers/my_module.rb, and rails c described in the issue, comparing a fresh initializer edit with later console starts. Trace how Spring and the Rails console load or reuse the initializer, and consider the issue resolved when MyModule.some_attr consistently reports 'some_val' without requiring an immediate initializer edit.

Description

bug

Hey Guys, I've recently posted a question on SO, but no one answers, I think that my issue is actually related to spring, here's the question:
https://stackoverflow.com/questions/48461291/ruby-on-rails-5-2-0-beta2-initializers-loading
Long story short: I have a custom (not from any gem) module in /lib/my_module.rb inside a rails (5.2.0.beta2) project, like this:

module MyModule
  mattr_accessor :some_attr
  self.some_attr = nil

  # Default way to setup MyModule.
  def self.setup
    yield self
  end
end

And I have an initializer for it, /config/initializers/my_module.rb:

MyModule.setup do |config|
  config.some_attr = 'some_val'
end

But when I run rails c I have MyModule.some_attr set to nil always, and only if I change something in MyModule initializer and nothing else after it, and run rails c immediately I have MyModule.some_attr set to 'some_val'.
