beautifying scss selector with colon in it adds space

[1aron]

Description

I use vscode extension "Beautify" and I know that it is based on "js-beautify"

Input

The code looked like this before beautification:

a:not(.color\:blue) { }

Expected Output

The code should have looked like this after beautification:

a:not(.color\:blue) { }

Actual Output

The code actually looked like this after beautification:

a:not(.color\: blue) { }

One more whitespace would make compile error !!
