Safari problem under Ventura 13

I can't find this issue referred to among the many problems with Safari. I'm not quite sure how to describe it, so I will also include a screenshot or two:

When I navigate to a website, then click on something specific on the website, such as a particular subject mentioned on a Wikipedia page, rather than hyperlink to that specific sub-article within Wikipedia, I am confronted with a drop-down bare page of slightly enlarged type from the sub-article, but without any accompanying images-just a large, bare page of text. This didn't happen two months ago, but it does now, and it doesn't happen in Google Chrome. I would like it to stop. It may be a result of some stupid move on my part, but I can't find a preference for it anywhere in Safari. See images: one shows what happens in Safari. The other shows what I get in Chrome.
