### Summary A commit sha in a comment is automatically turned into a link. In a MR comment, the URL becomes `[project_url]/merge_requests/[MR_id]/diffs?commit_id=[sha]`, but when editing and previewing the comment, the URL shows as `[project_url]/commit/[sha]`. ### Steps to reproduce Write a commit sha in MR comment. Before publishing (or after, by editing it), click on "Preview", note the URL the generated link points to. After publishing, note the URL of the link again. ### Example Project https://gitlab.com/Jellby/test/merge_requests/17 ### What is the current *bug* behavior? The links are *different*, which means the preview is wrong. Another question is which of the two links one actually wants. Personally I want the vanilla commit, not the MR diff... ### What is the expected *correct* behavior? I expect the preview to show the same link that will be in the final post, that's one of the purposes of the preview. I'd also like a way to get the link to the bare commit. ### Output of checks This bug happens on GitLab.com
