Reproduction steps
You will need 2 accounts for reproducing this since it relates to the unread indicator.
- Create a new forum.
- From account 1, create a post in the forum and ping account 2 in it to add it to the thread: pasted-image-1.png
- From account 2, open the thread you were pinged in by clicking on it in the channel list (NOT on the forum channel): pasted-image-2.png
- See that once you've read messages in the thread, the forum keeps its unread indicator even though there is nothing new to see anymore: pasted-image-3.png pasted-image-4.png
Expected behaviour
I expected the unread indicator to disappear once I've seen the new thread.
Actual behaviour
The unread indicator remains to be shown on the forum channel.
