BUG - No Icon shown for http://fritz.box/

When I open the config of my Router (http://fritz.box/) and add the credentials manually to Bitwarden (in the Browser extension in Microsoft Edge Chromium via “Zugangsdaten Hinzufügen”) thn this entry has no icon.

But the browser tab shows an icon and it is available via the default icon name:
http://fritz.box/favicon.ico
