This seems to have changed sometime today.
The link on an issue such as #2233507: Error Occurs On Add Form With Differently Named Single Bundle is now a comment permalink, which means it's not an anchor link on the current URL. Therefore clicking it causes the page to reload, which makes it pointless.

drumm#268374: "Jump to" links are broken on multi-page issues is the issue which made the change. It uses
entity_uri()to make the link, which we expect to give us a good URI. It is a valid URI, it gets to the correct comment. #2125397: Enable comment_fragment 7.x-1.x-dev to improve issue comment permalinks will make it a better URI.
