At times there may be data that's part of the additional_properties object which is part of the composer embed object that is needed to flesh out things in a powerup's views within composer. However Composer only passes the object's embed config to the powerup. Example:
Entire composer content_element object for a powerup item:
{
"_id": "KYSG4BAPBJDETHWMETQ6DHHMV4",
"additional_properties": {
"_id": "7FYQ5WN35JHKJL64EPUGKCDXXY",
"comments": [],
"livestory_author": "Bob Geldof",
"livestory_child_story": "FIIMZKPRKRGKNHXUOFUA6W2IGE"
},
"embed": {
"config": {
"dateTimeField": 1631117776129
},
"id": "timestamp-24691",
"url": "/"
},
"subtype": "timestamp_powerup",
"type": "custom_embed"
}
At present Composer only passes to the powerup views the embed.config object. In order to process the Live Article roll up data which is part of the additional_properties object we'd need access to it, but it's not passed over.

Thank you for submitting this idea and bringing this to our attention. I've added this for future consideration.
