I was considering filing this as a bug report, but then I thought, "I'm pretty sure it was designed that way." It just seems a bit odd having the comment be a link, too. Only the name of the media should be a link, which takes you to the comment in question—and in the current state, both link to comments. A good example I can think of to "compare" to is emails. In an email notification about a reply to a watched thread, the reply isn't also a link to the thread, only the name of the thread. I view it the same here. The comment shouldn't be a link.
