False positive on Style/RedundantLineContinuation #12627
Description
Expected behavior
File test.rb:
h = {very: {deep: {nested: {hash: false}}}}
val = h[:very] \
[:deep] \
[:nested] \
[:hash]
puts valRunning bundle exec rubocop test.rb --only Style/RedundantLineContinuation does not highlight any errors.
Running ruby test.rb produces the output false.
Actual behavior
Running bundle exec rubocop test.rb --debug --only Style/RedundantLineContinuation produces
C
Offenses:
test.rb:3:16: C: [Correctable] Style/RedundantLineContinuation: Redundant line continuation.

Running bundle exec rubocop test.rb --fix --only Style/RedundantLineContinuation removes the line continuations. After this, running ruby test.rb outputs:
{:deep=>{:nested=>{:hash=>false}}}
Steps to reproduce the problem
Create a file called test.rb containing the code from above. Run bundle exec rubocop test.rb --only Style/RedundantLineContinuation.
