[Thunderbird] dragging message to the desktop or a folder is not working

[ovari]

 * Nemo version: 4.2.3
 * Is issue with desktop or windowed nemo? both
 * Distribution: Mint 19.2 Cinnamon
 * 64-bit

Drag-and-drop a message from Thunderbird to the Desktop or folder (in Nemo) creates a "Link" file which does not work. The file that should be created is an email file with extension .eml.

This work with the Windows operating system. Not sure if this is a Linux Mint problem or a Thunderbird problem.
