[Frontend] Comment on any line in a changed file in merge request diff
Frontend Issue for: https://gitlab.com/gitlab-org/gitlab-ce/issues/13950
Please refer to the description of the parent issue for up-to-date information.
This issue was created to track Frontend weight independently of Backend and capture discussions.
Assuming the BE will be able to deliver the same kind of structure as we get now, Frontend needs to:
- Display lines sent by the backend (could be automatically handled)
- Allow the Comment bubble trigger to be shown on dynamically fetched lines after pushing
...the expand lines.
Heads up: original issue is not UX ready at the time of creating this so some UI tweaks might be necessary.
