Mountain Duck 5.3.2 | with Keep Offline selected, new SFTP server files stuck in "Sync in Progress"

[jterrain]

Steps to reproduce:

1. Using Mountain Duck 5.3.2 on Windows 11 25H2, connect to an SFTP server in Integrated sync mode.
2. Within that Mountain Duck bookmark directory, right-click a subdirectory "ABC" to select "Keep Offline on Local Disk".
3. Using a different tool, add some files to that remote directory "ABC" on the server.
4. Watch as Mountain Duck detects the new files and shows them in the local directory. However, the files remain perpetually in "Sync in Progress" mode and never complete downloading. Sync status shows "In Sync / Idle" and no data is being downloaded.
