Interesting! Though in this case Phanpy doesn't render the original for me either. Or do I have to make an account on their instance to make it work? https://img.sprovoost.nl/9f3e470b365cb2e0c9661208b5bf0f72fad5a42412824803702f84c3c914eaa1.png
Phanpy renders it inline, when you add the URL of another post to the content of a post. I guess the bridge doesn't do that. (There is no Phanpy instance, it's just a client for whatever Mastodon instance you want to connect to.)
It would look something like this: https://image.nostr.build/37d1839bf9af842aed6d5e5bdd4f4e0a4ea5113e10b2e732c9aca9991060a5b3.png
