Both download items point to the same physical file on disk, why should they differ?

The system is based on:

1. history information. This has nothing about the download state, it's just bare history plus the local file target
2. session information (from downloads.json), this is tracking in progress downloads, and as soon as a download is complete it gets removed.
3. file status, this just depends on the local file status

It's clear that once 2 is removed (download complete) and file status is restored, the old download will look like a normally completed download.

While one could make a case that cronological happenings are not preserved, I don't see a use-case for that, nor an obvious user benefit.
