Layout/EmptyLineAfterGuardClause inserts empty line outside of block, breaking method chaining

[afn]

The Layout/EmptyLineAfterGuardClause cop misbehaves in a situation such as this (very contrived) example:

# frozen_string_literal: true

def weird_sum(my_array)
  my_array
    .map { |item| next unless item.positive?; item * 2 }
    .compact
    .sum
end

Expected behavior

No empty line inserted, or an empty line is inserted inside the block.

Actual behavior

An empty line is inserted before the .compact line, resulting in a syntax error.
