A discussion is taking place about an issue with topics being marked as Unread when a tag is changed by the current user, despite the user being the one making the change. tvavrda has provided repro steps, including screenshots, and expects that the topic should not be marked as Unread for the user who made the change, but rather for others who can see the whisper post. Moin has also experienced a similar issue in topics where the last post is a whisper, even without tagging or enabling the setting. tvavrda mentions that this might be a more general problem, with other cases observed, but has only been able to reproduce this specific instance.
Expected behavior:
As it was YOU who changed the tag there is no need to put it into the Unread category. I think it would be correct to display for anybody else (who can see the whisper).
I noticed this issue in topics where the last post is a whisper, after I edited the content of the first post.
Without tagging and without enabling the setting.
