The following discussion from !215315 should be addressed:
- [ ] @mle started a [discussion](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/215315#note_2942232328): (+1 comment)
> @ms.mondrian @slashmanov **question** when comments are collapsed in merge requests we show the avatar of the commenter in the gutter area, is it possible to do the same for commits?

> {width=648 height=322}
>
> Eventually we should be without it there is no feedback that there are comments on the diff. I am open to when you would want to tackle this as part of this MR or a follow up.
