Patching Google Drive patch semantics

Google Drive's patch method doesn't work, and hasn't for over 3 years.

I'm not sure if this is why my attempts at changing the comments metadata with Drive.Comments.patch in Apps Script are failing - they seem to update (i.e. returning the modified resource) but then on a get request the resource is unchanged (a comment on a Google Docs file as specified by its commentId).

Must use X-HTTP-Method-Override: PATCH header.
