Creating an article while someone create the same one doens't create the fork

[pieer]

Problem

try to create a subject with user1, then start article creation with user2 and then user1, then submit article with user2 and then submit with user1 - ideally you have user2 as root and user1 as fork - but only one bubble shows. If you go from the user1 repo, then press bubble - you can see the intended root and fork (2 bubbles) but if you go from the subject then you only see 1 bubble.

Solution

we should see 2 bubble all the time
