Cannot mark notification as read from the dropdown

Unsure about version affected, the error happened in Area51, so that will tell the version.

I have the following situation:

1. I have a notification in my received notifications, it is active, so the number of active notifications shows as "1" . I open the notifications dropdown and mark it to be cleared. It clears, but when I reload the page, there it is again the same notification, active again.
