History dialog doesn't show changes from imported OSC file

[mikedld]

What steps will reproduce the problem?

1. Make changes in Vespucci, export as OSC
2. Open OSC file in JOSM
3. Select modified node/way and open its history (Ctrl+H)

What is the expected result?

History dialog shows all previous versions and currently modified version at the end.

What happens instead?

History dialog shows all previous versions but no currently modified version. At the same time, enabling "Modified objects" map paint style correctly highlights modified nodes/ways, and they have correct (modified) position and tags. Upload dialog also shows all changes correctly.

After saving changes as .osm and re-opening the new file, the behavior remains the same.

Please provide any additional information below. Attach a screenshot if possible.
