Style/WordArray does not report strings with hyphens

[beechtom]

Expected behavior

Word arrays with string literals are reported as offenses and rubocop suggests using %w or %W instead.

Actual behavior

Word arrays with string literals are not reported as offenses if any of the strings contain a hyphen.

Steps to reproduce the problem

flags: ACTION_OPTS + ['noop', 'execute', 'compile-concurrency']

With this word array, rubocop does not report any offenses.

flags: ACTION_OPTS + ['noop', 'execute', 'compileconcurrency']

But when removing the hyphen, rubocop does report a syntax offense.

Offenses:

lib/bolt/bolt_option_parser.rb:23:32: C: Style/WordArray: Use %w or %W for an array of words.
        { flags: ACTION_OPTS + ['noop', 'execute', 'compileconcurrency'],
                               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
