Vscode: Escaping \\ in snippet using \\\\ outputs only one backslash

• VSCode Version: 1.15.1, Commit 41abd2
• OS Version: Ubuntu 16.04

Steps to Reproduce:

1. Insert the following code snippet to latex.json (which is where user's tex snippet goes)
   Or by clicking File -> Preferences->User Snippets and search tex.

    "Input a multiline eqn": {
        "prefix": "eqnmultiline",
        "body": [
            "\\[",
            "\t\\begin{array}{lcl}",
            "\t\t ${1:foo} & = & ${2:foo} \\\\",
            "\t\t & = & ${3:foo} \\\\",
            "\t\t & = & ${4:foo} \\\\",
            "\t\\end{array}",
            "\\]",
            "$0"
        ],
        "description": "Input a multiline eqn"
    }

1. In a demo.tex, type eqnmultiline which will insert a code snippet as follows:

   \[
        \begin{array}{lcl}
             foo & = & foo \
             & = & foo \
             & = & foo \
        \end{array}
    \]

And I'm expecting a \\ at the end of the three foo lines, which I use \\\\ to escape. But the result is one \ at each line.
Snippet Grammer says using \ to escape \. So I'm wondering if this is a bug.

Reproduces without extensions:
Correct Sorry for not testing using suggested code --disable-extensions before because I missed that line in comment . Tried it today and after disabling extensions, I cannot insert tex snippets even through Command Palette. It tells me there are no entries to pick from
