      In the process of implementing WT-16561, I noticed that all the layered and cursor layered python tests were failing the checkpoint size check introduced in __wt_verify with extremely small discrepancies. Upon investigation I noticed that the ckpt->size was always greater than the accumulated the total_block_size of the btree by a difference that always matched the size of the root page.

      This ticket aims to investigate and confirm the cause of this discrepancy.
