As per title. Unlisted posts can not be reblogged, but the web UI still shows a reblog icon for such posts, and it can be clicked. After spinning for a while it then returns to its initial state, which is confusing (especially if you’re unaware of the limitation of reblogging unlisted posts).

The official mobile client does better: there such posts apparently don’t have the reblog icon. An alternative solution is Mastodon’s (web UI’s) way of showing a boost icon, but disabling it (so that it doesn’t react to clicks).

(The instance I’m on is pixelfed.social. The most recent post I had this issue with was federated from https://vernissage.photos/@magda/7470629220893329794#)
