Comments on outdated diffs in merge requests sometimes disappear from UI
Created by: ziima
We have encountered more than a few cases of comments disappearing from merge request UI. The comments are always linked to the obsolete diffs, usually they're new comments in the thread. We haven't been able to set up working reproduction process, but it looks like the Gitlab has troubles with comments added in the open merge request window, after new commits were pushed to the branch.
There are several ways the comments are missing, here is one of them:
- Pn merge request open in browser the old diff and old comments are shown with false note about outdated diff beneath them.
- When the allegedly outdated diff is shown, the new diff appears but without any comments.
But all the comments are listed in the Gitlab API.
