Title

Blockchain fully synced, but `bitcoin-cli -getinfo` shows `verification progress: 99.9999%`

Description

### Is there an existing issue for this? - [x] I have searched the existing issues ### Current behaviour Although the blockchain is synced, after some minutes, `bitcoin-cli -getinfo` does not display `verification progress: 100.0000%` any more, but drops to `99.9999%` and even below. New block arrived:  After two minutes:  After some more minutes:  Is there a technical reason for such a behaviour? Or is this just probabilistic assumption that maybe a new block could have been mined somewhere, but not delivered to a node yet? ### Expected behaviour When a new block was downloaded (and verified), the `verification progress` should stay at `100.0000%` and not drop with time – at least as long a new header is know to the node.  ### Steps to reproduce Wait for a new block and call `bitcoin-cli -getinfo`. Should display `verification progress: 100.0000%`. Wait some minutes and call `bitcoin-cli -getinfo`. Will probably display `verification progress: 99.999%` or below. ### Relevant log output 2023-11-10T19:29:22Z UpdateTip: new best=00000000000000000002cb8883317f93a44e213a584a62bf3ccef3274f22353c height=816190 version=0x32cb8000 log2_work=94.530644 tx=917108469 date='2023-11-10T19:28:52Z' progress=1.000000 cache=151.1MiB(1075120txo) 2023-11-10T19:29:20Z [net] Saw new cmpctblock header hash=00000000000000000002cb8883317f93a44e213a584a62bf3ccef3274f22353c peer=5 2023-11-10T19:29:20Z Saw new header hash=00000000000000000002cb8883317f93a44e213a584a62bf3ccef3274f22353c height=816190 ### How did you obtain Bitcoin Core Pre-built binaries ### What version of Bitcoin Core are you using? v25.0.0 ### Operating system and version Debian 5.1.127 x86_64 (MyNode 0.3.18)
