JS Beautify: preserve comment indentation

Question

I'm currently using the js-beautify plugin for SublimeText2 and editing the .jsbeautifyrc. I was unable to find an attribute in the config docs that I think is manipulable: preserve comment indentation.

My desired output matches my initial format:

// This comment isn't indented so I can fold all of the code it refers to
   function fooBar() {
      ... do stuff
   };

Comments may be nested in another function:

var fooBar = fooBar || (function() {
// Unindented comment for folding
   function fooBar() {
      ... do stuff
   };
}());

Or in a nested object/array:

foo: {
// Another unindented comment for folding
  bar: {
    ... more stuff
  },
// Yet another unindented comment
  baz: [
    ... even more stuff
  ]
}

I tried keep_comment_indentation to no avail.
