Why aren't the links in the body text... links? Really screws with accessibility.
But they are not common links, which is stupid. Hovering the "link" doesn't display the URL in the browser, right-clicking doesn't understand it's a link (because it's not), you can't open it in a new window as the creator of these "links" didn't consider that behavior (shift+click) and they are not accessible in the least.
TLDR: author re-implemented their own links, with more drawbacks than they could imagine
