Mastodon may expose followers-only posts to public. Is it a feature or a bug?
For example, this reply is addressed to the followers collection (to) and the mentioned user (cc):
https://not-brain.d.on-t.work/notes/admrkcvj3hfn5crj
But Mastodon says the reply is "public". Anyone can view it in this thread:

#Iceshrimp also doesn't require authorization, but you need to know the post ID to view it.
@kopper Did you know about this?
UPDATE: https://not-brain.d.on-t.work/notes/admrkcvj3hfn5crj is now addressed to public; apparently its audience was being modified by the originating instance depending on the delivery target.
