Merge request should only show diff for topic, not previous topics
For the following topology of changesets :
- [draft] (topic-2) add topic-2 feature
- [draft] (topic-1) add topic-1 feature
- [public] initial commit
When pushed to heptapod, two merge requests can be created. The first one is fine, only the diff for topic-1 is there.
For the second one it show both topic-2 and topic-1. It would be nice if it could only show topic-2.
A tricky part of this is then when I click merge on topic-2 one might expect to have:
- [draft] (topic-1) add topic-1 feature
- [public] (topic-2) add topic-2 feature
- [public] initial commit
