Maybe I haven't been paying attention, but I've never had a site attach extra text to copied text like this site does. I wanted to see what the test machine's case looks like, so I copied the make and model and pasted it into a search bar, and got "Read more:" and a link to the page along with the text I wanted to copy.
No thanks. I'll be skipping that site in the future, unless that javascript comes from a place I can easily block with pi-hole.
