Post action (via button or menu) resets the profile picture of the webhook post

Description

From , if the response of the message button contains update the prop "from_webhook": "true" will always be set. Which is not wanted if you e.g. use a bot account.
IMO this should just use the same logic as the other props: Copy it from the old post.
