Expected behavior

I would expected the safe navigation operator to be considered by Layout/MultilineMethodCallIndentation.

Actual behavior

The cop ignores method chaining when it uses .&.

Steps to reproduce the problem

test.rb

HakunaMatata.a
            .b
  &.c
  &.d

HakunaMatata.a
            .b
  .c
  .d

bundle exec rubocop --only Layout/MultilineMethodCallIndentation test.rb

only flags the second example.

RuboCop version

$ rubocop -V
0.52.1 (using Parser 2.5.0.2, running on ruby 2.5.0 x86_64-linux)
