When looking into T63725: Flow: Interlanguage links are losing the :colon prefix when saved, I noticed that the link https://www.mediawiki.org/w/index.php?title=Talk:Sandbox&topic_postId=rsg1m81vskkdywgk&workflow=rsftpxbkjdg745zu#flow-post-rsg1m81vskkdywgk displays the topic which title cannot be edited:
Note: the issue is not reproducible; at least I did not find the way to create the title with the same content - each link is on a new line.
- Go to the link: https://www.mediawiki.org/w/index.php?title=Talk:Sandbox&topic_postId=rsg1m81vskkdywgk&workflow=rsftpxbkjdg745zu#flow-post-rsg1m81vskkdywgk
- Click on Edit topic - the error message will be displayed.
