unexpected snippets behavior in vscode+latex workshop

I'm using vscode with the latex workshop extension, and I put the following in my latex.json file.

    "newcommand": {
        "prefix": "nc",
        "body": [
            "\\newcommand{\\$1}{$2}",
        ],
    },

I expected nc to expand to \newcommand{\}{}, with placeholders after the backslash and in the second pair of braces. However, I'm getting \newcommand{$1}{} with only one placeholder in the second pair of braces. Why is that? How can I get the desired behavior?

From the snippet doc

With \ (backslash), you can escape $, }, and \. Within choice elements, the backslash also escapes comma and pipe characters.

The following string is passed to the snippet engine: \newcommand{\$1}{$2}

\$ is interpreted as a literal $

We want the following string to be passed : \newcommand{\\$1}{$2}

Escaping this string for json gives

"\\newcommand{\\\\$1}{$2}"
