False negative for Rails/FormattedS with safe navigation operator

[mishina2228]

Expected behavior

I expect that Rails/FormattedS would be detected even if with safe navigation operator (&.), but it was not.

time&.to_formatted_s(:db)

(Without safe navigation operator, it is detected as expected.)

time.to_formatted_s(:db)

$ bundle exec rubocop sample.rb
Inspecting 1 file
C

Offenses:

sample.rb:3:6: C: [Correctable] Rails/ToFormattedS: Use to_fs instead.
time.to_formatted_s(:db)
     ^^^^^^^^^^^^^^

1 file inspected, 1 offense detected, 1 offense autocorrectable

Actual behavior

No offenses detected.
