When a viewer page was copied, each copy got its own annotationStorage entry, but newAnnotationsByPage was keyed only by source page. As a result, every output copy received all entries and reused their memoized references. Tag each entry with its rank among output copies of the same source page. The display and worker compute this rank independently; inserted documents preserve the order of copies. Keep unextracted entries at rank -1 so shared stamp bitmaps remain available without being written. Without ranks, new annotations are applied only to the first copy.
