----------------------------------------
If a method is refined for a subclass X of the owner of the method,
X.instance_methods(false) returns that method even if it's not defined
in X.


```ruby
class X
  def foo
  end
end

class Y < X
end

module Bar
  refine Y do
    def foo
    end
  end
end

p Y.instance_methods(false).include?(:foo) # false expected, but true is returned
```
