Notification cannot be marked as read
I have a notification. I click on it, but the notification doesn't go away. This always happens. (After a while, it does disappear, but I don't know when.)
For example, to get to the question There is no accept button?, I need to click on the notification. However, the badge doesn't go away after clicking it. This happens even though I click on it several times.
I use Firefox 75.0b11 (32-bit). There is no userscript being active on this site, and all site's scripts are enable.
