Clicking on the avatar of a user who's made a comment has stopped navigating to the comment
Whilst reviewing a pull request, it used to be possible to click the avatar of a user who had just made a comment, and the UI would scroll to the comment.
This has stopped working, and it's really annoying! It makes reviewing/responding to comments much more laborious.
Please fix it! (The icon/gravatar still updates with comment count, but clicking it doesn't do anything!)
