VS Code SSH user name cannot include the character \

Question

In Windows remote host I have username like WORK\username, and when I connect from Windows console:

ssh WORK\username@hostname

Everything is fine. Also I can connect from WSL with double slash:

ssh WORK\username@hostname

But I can not connect from VS Code. I have an error:

Could not establish connection to "hostname": SSH user name cannot include the character \.

What to do with it, I have tried to escape the slash in different ways, but it was not work.

My VS Code version is 1.59.1.

It can be solved, when the username is stored in ~/.ssh/config

HOST myServer
   hostname example.com
   USER WORK\username

Obviously the connection should be started then from the Remote Explorer.

Tested successfully with VS Code version 1.59.1 on Windows and also Linux
