If I remove `target_type=note`, only then DiscussionNotes show up. Additionally, `DiscussionNote` is not a supported value for the [param](https://docs.gitlab.com/ee/api/events.html#target-types) `target_type` ### Steps to reproduce 1. Create some merge requests in a project. Add general comments and start discussion threads 2. Make a request to the project events API `/projects/:project_id/events?target_type=note&action=commented` ``` curl 'https://gitlab.com/api/v4/projects/:project_id/events?action=commented&target_type=note' --header 'Authorization: Bearer <token>' ``` 3. Observe that results are returned that have `target_type` as `Note` 4. Make a request to the project events API `/projects/:project_id/events?target_type=note&action=commented` ``` curl 'https://gitlab.com/api/v4/projects/:project_id/events?action=commented' --header 'Authorization: Bearer <token>' ``` 5. Observe that results are also returned that have `target_type` as `DiscussionNote` ### Example Project https://gitlab.com/gitlab-org/gitlab ### What is the current *bug* behavior? Only general comments are returned with `target_type=note` ### What is the expected *correct* behavior? Comments in discussion threads should also be returned when `target_type=note` ### Relevant logs and/or screenshots {width=695 height=422} {width=700 height=422}
