Agile Web Development with Rails 7: "START_HIGLIGHT" instead of highlight in snippet (page 259)

On page 259 there is a code snippet with:

# START_HIGLIGHT
resources :support_requests, only: %i[ index update ]
# END_HIGLIGHT

I expect this is a typo in the markdown you use to add a highlight market next to lines, since that’s a line I would usually expect to be highlighted.
