The attachments link doesn't scroll to the attachments

Recently (maybe in build 8014, but I'm no entirely sure), the attachments link in a conversation* stopped scrolling to the attachments. When it's clicked, the browser scrolls down, but not to the attachment. You may require a long-ish conversation to see this problem.

(* If the original request/request description contains an attachment, the scrolling works).

The attachments link is e.g.

<a title="Scroll to Attachments" onclick="javascript:$viewWO.go2IDLink('thdAttachments_666063_reply');" class="bluetxt fsize12 fl" href="javascript:void(0)">Attachments(1)</a>

The div with the matching ID seems to be in the right place, but clicking the link scrolls to the wrong location.The go2IDLink function in scp.js seems to apply an offset to the scrolling position based on the id of the target; perhaps this is no longer appropriate and needs revision.

I've tested in IE 11, Firefox 53, and Chrome 58.

Cheers
