when editing any files over sftp by root user - SE dont save any changes in file, for example - ES Explorer with same login do it ok.

No errors, just no changes in any edited files.

Step to reproduce issue: connect to sftp - create empty file - edit - add some text - save - file saved - reopen - edit again - save - file saved BUT no changes inside((((

server debian 10, openssh via remote keys, any other software works fine.
