Filter on relationship route?

Is it possible to filter on a relationship route?

class PostResource < JSONAPI::Resource
  has_many :comments

  def records_for_comments(options = {})
    records_for(:comments).public
  end
end

class CommentResource < JSONAPI::Resource
  has_one :post

  filter :active,
    apply: -> (records, value, options) {
      if value
        records.active
      else
        records.inactive
    end
  }
end

This calls the filter:

/comments?filter[active]=1

This does not seem to call the filter:

/posts/14/comments?filter[active]=1

Start with the PostResource records_for_comments method and compare filter handling for /comments?filter[active]=1 versus /posts/14/comments?filter[active]=1. Trace the nested relationship route entry point and confirm whether the CommentResource active filter is applied there; done means the nested route produces the same filtering behavior as the direct comments route.
