Entity Creation Field Data Not Sent by Webhooks

I’ve noticed that when creating a new entity such as a Shot and entering field values like ‘code’ in the “Create a new Shot” dialog box, the Event Log Entry List shows one “new_entity” entry for the entity creation with its id, and then subsequent “attribute_change” entries for each field that was included on creation.

However, in Webhooks the only payload that is ever sent is the initial “new_entity” through my Shot: Created webhook, and the “attribute_change” events are not picked up by my Shot: Update webhook that monitors field changes. If I wait to add any field values until after creation, through the UI, then the Shot: Update webhook triggers correctly.
