[BUG] Not all comments seem to always load

[Athlon007]

Describe the bug
It seems like some comments never get loaded when opening a post.

Expected behavior
All comments should be visible.

API requests might be missing a type_ parameter:

• Comments load if we pass type_=All.
• For example: The following request returns zero comments if we don't specify type_=All -> GET https://lemmy.world/api/v3/comment/list?post_id=1719940&sort=Top&page=1&auth=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOjU1MTU4LCJpc3MiOiJsZW1teS53b3JsZCIsImlhdCI6MTY4OTcxMzE2NX0.gQf0aT0gg-dezBnpc2msE2BQsqQzuJ9h5wmD1cDVSCk&type_=All`

Relevant API doc: https://join-lemmy.org/api/types/ListingType.html

• Not sure which parameter is most appropriate: "All"|"Local"|"Subscribed"
• For this particular example (above comment), "Local" also returned 0 comments, only "All"/"Subscribed" returned the same set of comments.

After specifying "type_=All", CommentService now gets all comments, but it currently filters out comments, so child comments don't get rendered after being downloaded.

Should be fixed in #82
