When a new document revision is created, the bounding boxes from previous AI runs (Playbooks, Metadata, or Chat) are invalidated. Users can click the reference but will not be brought anywhere in the document.
In the future, it would be nice if:
When the edits are made to a different node, the bounding boxes are maintained
When the edits are made to the node which the bounding box referenced, some indication is given that this part of the document has changed so the AI output may not be correct.
