Default [Q] [Stock 4.4.2] Endlessly repeating notification sound, expected behaviour or bug?

Hello there,

After updating to 4.4.2 stock on my Nexus 4, the default notification tone is set to argon for sms gmail etc. However this tone seems to repeat itself until the corresponding notification is cleared by pulling down the notification bar (ie 4 hours of argon tone repeating while i sleep).

How is the situation in your stock 4.4.2 Nexus 4s? Am I the only one having this?
