I love your trick and I use it in some notebooks https://observablehq.com/@pac02/an-introduction-to-observable-for-wikidata-users and https://observablehq.com/@pac02/explore-gender-diversity-in-a-single-wikipedia-article. It seems that it's not working anymore. There is a CORS error.

thanks i resolved it by disabling the non-wikidata cell modes

Congrats. You rock !
