auto-correctすると要素が消える

[booink]

-v 0.60.0 で、auto-correct時に要素が消える現象が起きましたので、報告致します。

auto-correct前のソースコード

# frozen_string_literal: true

hoge = Hoge.new(
            { hoge: 'hoge',
              fuga: 'fuga',
              foo: 'this is dummy.'
            })

auto-correct後のソースコード

# frozen_string_literal: true

hoge = Hoge.new(
  hoge: 'hoge',
  fuga: 'fuga'
)

Hoge.new時にキーワード引数ではなくHashで渡しているのがイレギュラーではあると思いますが...
