What happened?

See screenshot. On the right is the "prototype" actor with an item that contains a content link using a relative uuid (generated automatically via drag-and-drop) to another item in their Items collection.

On the left is a synthetic actor created from that prototype actor. I did confirm that the ids of the embedded items are unchanged.

This is (probably?) the cause of these issues:
foundryvtt/dnd5e#4755
foundryvtt/dnd5e#4988

Reproduction Steps

1. Create an actor with prototypeToken.actorLink: false.
2. Create two items on the actor.
3. Drag-and-drop item A into a text editor on item B. (This creates a link using relative uuid.)
4. Then plop the actor onto the canvas.
5. Open the sheet of this synthetic actor. The created content link does not resolve.
