As a user I want to mark notification as read so that I am no longer distracted by notification alert
Acceptance Criteria
When User opens the most recent notifications popup and there are any unread notifications displayed, then those notifications should be considered as read and the notification counter value is decreased by the number of those notifications (no more than 3 at once)
When User views All notifications page, he should see the backgrounds of unread notification coloured green and read ones coloured grey
If user refreshes the page or leaves and returns later, all the notifications that he viewed during the last session are considered read
If user has already seen some new notification in the Most recent notification popup from the menu bar, then those notifications are considered as read
Example: if user has reviewed the notifications in the Most recent notification popup and by the moment he opens All notifications page some new notifications come, then he may see some grey notifications between green ones
