I intended those to be a short list of relay host names. But the pic on the right looks like the client rendered them to make URL previews. I think it's just the way that client interprets host names without the protocol notation(wss://). I bet if I included the protocol notation it wouldn't have rendered them as URL previews. Let's try...
wss://relay.damus.io
wss://purplerelay.com
wss://rocky.nostr1.com
