Oh, my mistake, it's been a while since I wrote the code. I use it to style the linked comment. So, the browser automatically scrolls to the appropriate location, and then jQuery adds a style to that comment so the user can easily locate it, or refind it if they scroll up and down the page.

In modern browsers, you can sometimes achieve this effect with `:target`. (https://developer.mozilla.org/en-US/docs/Web/CSS/:target)
