Autocorrection of Rails/HttpPositionalArguments removes keyword-splat arguments

[shepmaster]

Expected behavior

There would be no change to the code.

Actual behavior

The code is corrected in an incompatible manner

Steps to reproduce the problem

Gemfile

# frozen_string_literal: true

source 'https://rubygems.org'

git_source(:github) { |repo_name| "https://github.com/#{repo_name}" }

gem 'rubocop-rails', '=2.8'

.rubocop.yml

require: rubocop-rails

AllCops:
  NewCops: enable

spec/controllers/my_controller_spec.rb

# frozen_string_literal: true

describe do
  [{ format: :json }, { format: :html }].each do |args|
    it do
      get :nothing, **args
    end
  end
end

Run rubocop:

rubocop -a
