As I understand there is a connected issue fixed for Github. Is it possible to adopt the same fix for Gitlab or is it completely different?

I would certainly examine the linked PR to see if it teaches you anything, but I wouldn’t expect it to necessarily be exactly related. The fundamentals of cross-provider DangerJS behavior has been pretty stable for a long time. GitLab is a relatively newer provider so I’d expect the issue to be in one of these places:

• https://github.com/danger/danger-js/blob/main/source/platforms/GitLab.ts
• https://github.com/danger/danger-js/blob/main/source/platforms/gitlab/GitLabAPI.ts

I think more likely, the problem is a misunderstanding about GitLab’s automatic behaviors, for example maybe GitLab has only one “slot” for a line-level comment, which means the last one always wins. In that case, you might be able to preprocess all the line-level comments, and merge all the ones that target the same/file-line into a single comment. (I even believe this is doable in user-space)
