Update:
This was originally posted as a feature-request, but further investigation leads me to believe that this is a bug.
Chat notifications are allegedly supposed to appear in the top bar after 15-20 minutes, but this behavior is currently not working for the new top bar.
To confirm this, BoltClock originally waited 40 minutes to see if he would get a notification. He did not. As an added test to double confirm it, he then pinged me and I waited over 60 minutes and had the same results: no notification on the new top bar.
While browsing around waiting, I did notice something: notifications still work on the old top bar. Currently, the Area 51 proposals page still has the old top bar. I have a notification there:
The Area 51 Discuss page has the new top bar rolled out. No notification in sight there:
I tried multiple pages with the new top bar with plenty of hard refreshes. The message does get listed in my inbox, but there is no notification for it on the new top bar:
Original Post:
As pointed out in chat by someone else, there is no longer a notification icon in the top bar when someone pings me in a chat room.
There will only be a notification if I'm in a chat room, or the classic "chat top bar" notification icon will appear once I visit a chat page:
I think removing this from the (non-chat) top bar is a step in the wrong direction. Can we have that back?
