For GNOME Flashback, this is fixed in version 3.37.1, available in Ubuntu development release (Groovy).
It cannot be backported to 20.04 (Focal) because it needs changes in Nautilus that are only available in Nautilus 3.37.1.1.
I guess a fix for gnome-shell-extension-desktop-icons in 20.04 will be impossible for the same reason.
