Not a bug Reply to thread doesn't result in notification/alert, and the thread and subforum do not get bolded as expected

I made a number of comments here reporting multiple scenarios where the buggy behavior occurs: https://xenforo.com/community/threads/not-receiving-some-alerts.189866/post-1730352

This may be one cause:
Oh, I think I may have thought of a possible cause:

1. OP makes a thread.
2. User2 reacts to the thread and writes a comment that goes into the mod queue.
3. OP gets an alert for the reaction, clicks it, and visits the thread which resets some internal "mark thread as read date".
4. Moderator approves the comment replying to the thread.

Expected behavior would be for 4. to result in another alert, and the thread and subforum to bold. But possibly due to the way Xenforo is calculating "thread read" is causing this problem.

If that's correct, a solution may be for Xenforo to trigger alerts and "new post" indications after certain moderator actions.

I noticed that sometimes there's a checkbox for an admin action to "notify people subscribed to thread", so my guess is that's not a default when it should be, especially since that checkbox is only sometimes available. You could change it to make that the default behavior and change the checkbox where it exists to "don't notify people subscribed to thread".
 
This is generally as designed. We only send new reply alerts when a message is appended to the end of a thread that you have previously fully read. In the scenario described, you would still receive the alert if it were the newest post at the time of approval. Additionally, you would still receive an alert regardless if the approved post had quoted your post. The moderator checkboxes are generally for alerting the author of moderator actions (or for forum watchers when moving a thread).
 
I tested the exact steps described before triaging and received it just fine, and we’ve received no other reports of this. If you can reproduce this reliably with all add-ons disabled on the latest version, you can share the steps and I can try again.
