Confusing message for `Rails/RootPathnameMethods` in `Dir[]`

[Tietew]

RuboCop suggests confusing solution on following code:

files = Dir[Rails.root.join('path/*')]

Expected behavior

RuboCop suggests to rewrite Dir[Rails.root.join(...)] to Rails.root.glob(...) as autocorrection does.

Actual behavior

RuboCop suggests to append #[].

files = Dir[Rails.root.join('path/*')]
        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
C: [Correctable] Rails/RootPathnameMethods: Rails.root is a Pathname so you can just append #[].

But appending #[] is an incorrect solution.

Note

Autocorrection works correctly. The issue is only in the message.

# bad
files = Dir[Rails.root.join('path/*')]
# autocorrect
files = Rails.root.glob('path/*')
