If the discussion is created on a line that doesn't appear in the diff, then the discussion doesn't appear in the diff view, only the timeline view. I want to get the diff of a file using GraphQL, but as far as I can tell this is not available. This does appear to be available in the REST API though: https://docs.gitlab.com/ee/api/merge_requests.html#get-a-single-mr-diff-version
