TM scope error with IIFE using JavaScript ES6 arrow function

[jlmakes]

Regular IIFE (Correct):

ES6 Arrow IIFE (Incorrect):

Above on line 1, the fragment = (() =>, the inner ( is missing the punctuation.definition.parameters.begin.js scope.

Subsequently, on line 3 the ending )() is missing meta.brace.round.js

---

• VSCode v1.17.2
• OSX v10.11.6

Steps to Reproduce:

1. Create any immediately invoked function expression, using an ES6 arrow function.
2. Use a theme that colors punctuation scopes differently (such as Duotone)

Reproduces without extensions? Yes

(However, no built-in themes visually show the problem, you must use the scope inspector.)
