I was notified from three different wikis in the past day. When I opened the menu for the first time (from a blue number badge), the messages were shown. On later page views, the number badge was grey. I don't quite remember what this means, but I think it means I've seen them but not marked as read.
When opening it from the grey badge, I no longer see the messages. It only shows the names of the wikis they are from, but the message that used to be there is missing. Looks like some state is inconsistent? Either the messages should be gone or be there with both the wiki section and the message itself.
|1. Click on number badge||2. Click "View 3 notices"|
Problem: The three notices are missing.
|3. Click blue dot for "Mark as read"|
|4. The three notifications go away (as expected), and the number badge goes away (as expected)|
|5. Number badge came back (Problem)||6. Notifications came back unread (Problem)|
At this point, one can resume from step 1 and go through the same loop again.
