IndentationConsistency with "EnforcedStyle: rails" does not work in Rails concerns

[5t111111]

In Rails concerns, IndentationConsistency with "EnforcedStyle: rails" does not detect incorrect indentation.

---

Expected behavior

concern :Authenticatable do
  def foo
    puts "foo"
  end

  private

  def bar
    puts "bar"
  end
end

In the above code, the method bar should be indented to 1 more depth, but Rubocop does not complain about this.

Actual behavior

No inconsistent indentation is detected.

Steps to reproduce the problem

1. Set IndentationConsistency with EnforcedStyle: rails in your Rubocop config
2. Write the code contains inconsistent indentation in a concern block (the one in "Expected behavior" for example")
3. Check the code by running Rubocop

RuboCop version

Include the output of rubocop -V:

$ rubocop -V
