Unexpected behavior when `frozen?` method is defined in model

[kenzo-tanaka]

Hi👋 First of all thank you for the very helpful gem! I found an unexpected behavior while using draper and would like to report it. When the frozen? method is defined in the model, the decorated instance returns false.

The following is a sample code.

# app/models/user.rb

class User < ApplicationRecord
  def frozen?
    true
  end
end

class UserDecorator < Draper::Decorator
  delegate_all
end

rails console
irb(main):001:0> User.first.decorate.frozen?
   (1.2ms)  SELECT sqlite_version(*)
  User Load (0.2ms)  SELECT "users".* FROM "users" ORDER BY "users"."id" ASC LIMIT ?  [["LIMIT", 1]]
=> false  # expected true

I'm sorry if I misunderstood something about this behaviour🙏

Hi @kenzo-tanaka seems this is a ruby thing rather than a draper issue. If you call frozen? on the object without decorating it still returns false as long as you didn't freeze the object.
