First it compares local and remote directories to find differences.
Then it transferes files that are different.
Sometimes during synchronization the server disconnects.
If the synchronization has reached the transfer file phase then it reconnects and continues transfering files where is stopped.
On the other hand if synchronization is still comparing local and remote directories then it does not continue.
If a disconnect happens during the compare phase, I would like winscp to reconnect and continue to compare directories where it left off.
Parameters to use for the compare reconnect could just be the same as exist already for file transfer reconnect.
