editing comments destroys multi-word "@" handles

Avatar

The comment interface has the nice feature of providing a pop-up list when an "@" is typed, from which an addressee handle can be selected. Works great, when a comment is initially being entered. But if that comment is subsequently edited, multi-word handles (such as my own, "@G H") are corrupted to be just the first word of the handle, e.g. "@G" H. This not only links to an incorrect person if such a handle exists, but incorrectly informs that person that they were mentioned in a comment.
