The 0.27.22 release stabilizes source-element IDs during chunk serialization.

The official source reports this update: 0.27.22. This release rolls up all changes since 0.27.16. Fixes Faster chunk serialization with stable source-element IDs. Avoid copying orig_elements twice during serialization. IDs minted during serialization now remain stable across calls, including inside orig_elements ; explicit and hash-derived IDs are unchanged. ( #4472 ) Preserve figure and table images with differently ordered coordinates. Derive crop boxes from coordinate extents to avoid invalid boxes and silently dropped images. ( #4371 ) Handle empty XLSX worksheets without crashing. Empty sheets yield no connected components and partitioning continues.
