Operators like in and of are not colored properly with one-light-syntax

[j-f1]

The code here matches the operators:

gandm/language-babel/grammars/Babel Language.json lines 1197–1200

{
  "match": "(?<!\\.)\\s*+\\b(delete|in|instanceof|new|of|typeof|void|with)\\b",
  "captures": {
    "1": { "name": "keyword.operator.js" }
  }
},

However, one-light-syntax only colors certain keywords from blue to purple:

atom/one-light-syntax/styles/syntax/javascript.less lines 2–16

.syntax--keyword.syntax--operator {
  color: @hue-1;

  // keywords are definded in https://github.com/atom/language-javascript/blob/master/grammars/javascript.cson
  // search "instanceof" for location
  &.syntax--delete,
  // ...snip...
  &.syntax--void {
    color: @hue-3;
  }
}

In language-javascript, the name of the operator is added as a scope:

atom/language-javascript/grammars/javascript.cson lines 960–963

{
  'match': '(?<!\\.)\\b(delete|in|of|instanceof|new|typeof|void)(?!\\s*:)\\b'
  'name': 'keyword.operator.$1.js'
}

Could this behavior be replicated in language-babel?
