Just checking the status of this bug, it seems to have been lost among the tag bug. (also still have not received a notification of either type since finding the bug, may just need to create an alternate account to do that)
We're working on Echo (the notifications) now, so hopefully this will be resolved. I'll look into the tag issue as well.
The issue is now fixed in notifications. Past notifications still link to [No page] though
Although, notifications no longer seem to be displaying the new notifications number.
