hangout notification does not wake screen

[monkeycsk]

when i get a hangout notification while the screen is off (sleep mode), the screen does not wake up and i only get a notification light.

when i get a regular text via the messaging app, the screen wakes up.

is this a bug with note 8 or with hangout????
