Fix https://gitlab.com/gitlab-org/gitlab-ce/issues/33868 While in a MR "Changes" tab looking at some diff note discussions. Clicking reply and pressing the up-arrow should edit your last comment in that discussion. I suspect this regressed in https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/11173/diffs#f4bb984ec495c5cb58516785c62978f5209c39b4_179_178 where we changed the selector
Closes #31348
