i got it to work for a singleton class this way:

```plaintext
# my overrides.rb

# A module that will be prepended into TopicEmbed.singleton_class
module TopicEmbedOverrides

  # Override parse_html method
  def parse_html(html, url) # note: i dont use self. here
    # my new stuff here
    # then run original implementation
    super
  end

end

# do the override here
class ::TopicEmbed
  singleton_class.prepend TopicEmbedOverrides
end

```
