Expected behavior:
Under the social links for a staff user, the Bluesky entry should allow for a URL that uses the DID and not a current username.
Resulting behavior:
Ghost will not allow the URL, declare it invalid (when it is not invalid), and not save it.
The part for entering a URL for social links in the staff profiles for Ghost only allows Bluesky links to go to user URLs and not the DID, which stays persistent. It does not redirect the URL, but it shows the current profile of that person. You can see the current username/handle.
In Bluesky, your DID is your true self, so to speak. Mine is did:plc:mjnnvz4dw6yqbvubajnflarj. When you type https://bsky.app/profile/did:plc:mjnnvz4dw6yqbvubajnflarj that will show my profile, even if change the username from il-kwang.bsky.social to something custom, such as jonathan.custom-website.com.
If I use https://bsky.app/profile/il-kwang.bsky.social after I change the username to something else, then it will not work.
Even worse, if I do change the name and do not create a new account with the old name of il-kwang.bsky.social, then someone else could create that and impersonate me by becoming the new target of any and all links with that username and not the DID.
