Can't get rid of a notification

As seen in the image, I have a notification from myself(I guess I tested the comment feature). But now it won’t disappear. Clicking on it won’t help. I restarted and rebuilt the docker container (only API and frontend not database).
Is this a known issue?

Did it only appear recently? Or are you living with it since two months?

I’m living with that for two months now.

If I remember correctly, I tested the comment feature and I noticed the notification, but I deleted the comment without clicking on the notification.

Now implemented in 10c9913e12 and ff2b4b8bf4. Please verify with the next unstable build.
