Answer comment links from activity page don't work (take you to the page but not the comment) #404
Description
On a user's activity page, links to comments on answers are of the form: posts/qid#answer-id#comment-id. These links don't take you to the comment. The author of this question says it's because of the two '#' characters in the URL.
We already support a different formation for a comment URL: posts/qid#comment-id. We use this working form in notifications; could we also use it in the activity list?
