• Alice makes a post.

• Bob shares Alice's post, adding his own reply.

• Alice disables shares on her initial post. Bob's reply still has a visible share button.

• Charlie tries to share Bob's reply. After composing their own addition to the thread, Charlie notices that the "post now" button doesn't appear to do anything.

• Charlie instead tries to quick-share¹ Bob's reply. The rebug icon turns orange, and the post does not get shared. Charlie checks the browser dev tools, and sees the following 500 server error in the network traffic log:

[{
  "error": {
    "message": "Can't share a share of a post with shares disabled.",
    "code": -32603,
    "data": {
      "code": "INTERNAL_SERVER_ERROR",
      "httpStatus": 500,
      "path": "posts.quickShare"
    }
  }
}]

So it seems that disabling sharing on a post also disables sharing for any replies to it, but the UI doesn't indicate that change.

(Note: Yes, I am fully aware staff have more important things on their plate right now)

1. Shift-click the rebug button, skips the post composer and just rebugs right away.
