Merge request comment thread updates that aren't comments is inconsistent
# Problem When filtering Merge Request comment threads by `comments only`, there is an inconsistency of showing non comment updates like version change information. Scenario: 1. On Activity, `Sort or filter` to `Show comments only`. 2. Go to the root Merge Request URL - such as: https://gitlab.com/gitlab-org/gitlab/-/merge_requests/98438 3. Go down to a message thread that has had a non-comment update - such as this one: https://gitlab.com/gitlab-org/gitlab/-/merge_requests/98438#note_1139929841 (important, don't go directly to that link, the issue only appears if there is no anchor in the URL) 4. Notice the update message below isn't present. ![screen_shot_2022-10-20_at_11.11.24_am](/uploads/5f7fbf64160d89fe2b403063ea3b3184/screen_shot_2022-10-20_at_11.11.24_am.png) 5. Now observe the update is present if the anchor is in the url - click on link directly and observe: https://gitlab.com/gitlab-org/gitlab/-/merge_requests/98438#note_1139929841 /cc @phikai
