Why are certain newspapers not loading in Safari on Mac?

I read several news sites on my MacBook Pro (Sequoia 15.0.1) running Safari (18.0.1). ~3 months ago, certain sections of "The Times of London" stopped fully loading and some photos had to be opened in a separate tab. I switched to reading the site in the Google Chrome app; i.e. not through Safari, and "The Times of London" site works fine. A couple of day ago, the same problem occurred with "The Wall Street Journal". Once again, switching to the Google Chrome app resolves the problem.

Anyone know how to get the sites to load properly Safari?
