Null file permissions are not preserved on copying / moving between different filesystems

I'm running mc-4.8.25-3.fc33.x86_64.rpm and I've noticed quite a nasty bug:

I've just copied /etc/shadow to a new location at the same file system and the permissions have changed from 000 to 644 which is a critical security bug. The preserve attributes checkbox is enabled:

[x] Preserve attributes

The application is running under root.

If either of user/group/other read/write bits are on, permissions are preserved.

The bug is also reproducible when moving a file to a different filesystem.
