Take the following code in ruby 3.3.0:

module A
  def print
    puts "A"
  end
end

module B
  def print
    puts "B"
  end
end

class C
end

c_instance = C.new

C.send(:include, A)
c_instance.print

C.send(:include, B)
c_instance.print

C.send(:include, A)
c_instance.print

I expected it to print out:

A
B
A

But it prints out

A
B
B

Why is that?
