When performing a contact import from a CSV file that contains a mapping to the Notes, the note is successfully imported (and set up as the first note for that new contact).
However, it shows that the note is "created by:" that user. For example if Joe User imports a new contact named Jim Contact, the first note for Jim Contact will be "created by:" Jim Contact. This does not make sense: it should assume that the user doing the import (and thus the change) has created that note.
Specifically, in terms of the fields, it seems that when a contact is imported, in the civicrm_note table, contact_id is automatically set to entity_id. However, this is undesirable behaviour. contact_id should be set to the user doing the import (and thus the user creating the contact in the first place).
