Email notification link doesn't link to respective message, but to most recent one

Hi, running Private Messages on a fresh WP install. Another issue i came across:

The link in the notification email for a new message contains a link with a message ID. e.g. "Check your messages here http://wp.url.com/inbox/?message_id=29".

However this ID doesn't seem to have any effect. To my understanding it should link directly to the message in question, instead it just opens the inbox with the most recent message selected. Shouldn't it select the message with ID 29 in this case or am i reading too much into the ID?
