Steps to replicate the issue (include links if applicable):
- In the same minute, post a message with the same title on several different talk pages.
What happens?:
- When you subscribe to one discussion, you automatically subscribe to other ones.
- Only one topic is displayed on Special:TopicSubscriptions.
What should have happened instead?:
- At least, all related talk pages should be displayed on Special:TopicSubscriptions.
- Maybe we should also allow to subscribe to only one of those discussions.
