code in extras/ isn't reloading

[pushcx]

In config/application.rb we configure the autoload path with a line of code straight out of the guide: https://guides.rubyonrails.org/autoloading_and_reloading_constants.html#config-autoload-paths

    config.autoload_paths << "#{root}/extras"

Despite this, files in extras are not reloaded on change, making dev tedious. This is in development mode (which does not change the default of config.enable_reloading = true).

While this is a good first issue if you are new to the codebase, this is probably not if you are a junior dev. This is maybe a weird bug in Rails or maybe some kind of subtle, accumulated misconfig based on our years of updates from Rails 3.2.2. Or maybe I'm staring through some obvious typo in the word "extras", I don't even know anymore after how many times I've lost time kicking this around.
