private method called explicitly through self should return an error, but in version 2.7.1 an error does not occur and the method is executed

class Person
  def speak
    puts "Hey, Tj!"
  end

  def whisper_louder
    whisper
  end

  def whisper_self
    self.whisper
  end

  private 
  def whisper
    puts "His name's not really 'Tj'." 
  end 
end

p = Person.new

p.speak
p.whisper_louder

# should cause an error
# but in version 2.7.1 no error occurs
p.whisper_self
