Nothing happens when I select this menu item.

In the terminal, I get

{{ qt.qpa.wayland: Non-toplevel surfaces can't request window states }}
{{ D: 20:22:52,328 /usr/lib/python3.7/site-packages/picard/browser/filelookup.launch:58: webbrowser2: https://musicbrainz.org:443/taglookup?artist=G%C3%A9za%20Anda%20-%20Ferenc%20Fricsay&release=Radio-Symphonie-Orchester%20Berlin&track=&tracknum=&duration=&filename=&tport=8000}}
