Marking a notification as read on mobile does not update the icon flashing on the open desktop client

It would be nice if it could update the icon flashing when notifications are marked as read on mobile. Currently when you have both desktop and mobile clients open at the same time then read the message on a mobile device, the ping counter decreases (if it was a mention) on the icon for desktop, but the flashing does not go away. The flashing should only go away if there are no unread messages that are set to notify.
