// CreateMemoComment carries the COMMENT relation to its parent memo. The comment
// memo is converted before the relation is created, so without an explicit reload
// the returned memo (and the memo.comment.created webhook payload built from it)
// would have an empty Relations slice. Regression test for usememos/memos#6081.
