Recipe for Ars Technica only loading top level headings

I've been enjoying a great recipe for Ars Technica for many years. Really appreciate Darko Miletic, Sujata Raman, Alexis Rohou, Tom Sparks providing and maintaining this over the years.

I am experiencing a problem similar to the one posted 09-02-2016, by renszarv and I think fixed back then by Kovid Goyal.

Since late August 2024, the Ars Technica recipe is returning only the top level headings; content is absent.

[I am using Calibre 7.17, but I noticed this problem on the previous release as well]
