Android navigation or how they broke notifications

A lot of the sessions were streamed at Google IO but a lot of interesting ones were not. I finally watched the navigation talk and am a little distressed to see they have broken notifications.

A couple of times a day I receive notifications for Gmail and what not. I click the notification , read the email and then press back to go to my previous app. Starting with Jelly Bean this will no longer work. It makes me :(
