Steps to reproduce the problem

# .rubocop.yml

AllCops:
  NewCops: enable

Layout/MultilineMethodCallIndentation:
  EnforcedStyle: indented

# frozen_string_literal: true

self.bar =
  baz
    .gsub(/\s+(?=$)/, '')
    .gsub(/([,;]|\.{2,})(?=$)/, '.')

(just removing self. leads to no offenses)

RuboCop version

Include the output of rubocop -V or bundle exec rubocop -V if using Bundler.
If you see extension cop versions (e.g. rubocop-performance, rubocop-rspec, and others)
output by rubocop -V, include them as well. Here's an example:

1.26.0 (using Parser 3.1.1.0, rubocop-ast 1.16.0, running on ruby 3.1.1 x86_64-linux)
