Same since upgrading to 7.0 on my GS7. To summarize, opening an email from the notification bar doesn't make the notification go away. To make it go away, I can push "back" and go to the inbox, which would clear any notifications anyways (say I have 5 unread and I open the gmail app directly, it will clear the notification). Or, tapping the notification again makes it go away.
However, if I open the notification and then go do anything else besides push back or re-tap the notification (open another app from the notification, go to home screen, or use the app switcher) - aka, do normal behavipr - it stays there.
