Refinements behavior is broken

[ruby-core:100070]

Description

Calling the methods defined by Refinements via super from a singleton method breaks the behavior.

class X
  def hoge
    ["X#hoge"]
  end
end

using Module.new {
  refine X do
    def hoge
      ["refine #hoge"] + super
    end
  end
}

x = X.new

def x.hoge
  ["x.hoge"] + super
end

# Refinements method is not called
p x.hoge
# 2.7.1 => ["x.hoge", "refine #hoge", "X#hoge"]  OK: Expected behavior
# 3.0.0 => ["x.hoge", "X#hoge"]                  NG: Behavior is broken.

# Method#super_method refers to a Refinements method
p x.method(:hoge).super_method.call
# 2.7.1 => ["refine #hoge", "X#hoge"]
# 3.0.0 => ["refine #hoge", "X#hoge"]

This is broken by a fix for [Bug #17007].

Is this the intended change?
