Is it worth considering putting this into the gem instead?

I'd like to do so but not this version, this version isn't well supported. This one: https://github.com/alphagov/accessible-autocomplete - is worth putting into the GEM

In terms of actual components, there's also this one in smart answers, which is a very trimmed down simpler version, again based on the same original code: https://github.com/alphagov/smart-answers/blob/main/app/views/components/_autocomplete.html.erb

That's interesting (didn't know this), I'll work on getting these into the components gem
