World Clock "Add a New World Clock" input matching doesn't suggest timezones, making it impossible to add new world clocks
In gnome-shell 3.30.2/3.32.2 on Fedora Worktation 29/30, the "Add" button for the world clock dialog of the standard gnome-shell clock applet in the top bar doesn't work. If I want to add a city, and start typing in the dialog, I don't get suggestions of cities to add and as a consequence, the "Add" button stays greyed-out. So I can't add any timezone/city to it. The cancel button works fine but the Add button doesn't. It is illustrated in this screenshot:
