Observe the 15 seconds it took my (reasonably fast) machine to import the remaining blocks. This is a problem for me since my application relies on this field to determine if syncing is complete. We can not rely on getblockchaininfo.verificationprogress either due to #26433
To reproduce
Start a node that hasn't been synced in a while and observe the log output.
System information
Observed on version 22 from the website.
