Does using a photo from Google Photos in a Google Doc cause it to be counted twice against the storage allocation?

Photos in Google Photos count against the storage allocation for the account
(though some have a billing waiver in effect, if taken on a Pixel phone).

If such a photo is incorporated into another Google product, such as Google Docs, does each use count anew for storage? Are Pixel photos charged or free, when incorporated into a document?

Has anyone done the experiment?
