Inner parentheses do not get colored

[boris-petrov]

In this JavaScript example (just paste the code in an a.js file):

foo([],
	function () {
	return bar({
		baz: function () {
			return [];
		},
	});
});

None of the parentheses ((), [], {}) get colored in lines 2 through 6 included. That is, only the first and last lines have their lines colored. I guess this is a bug and a major one. Or perhaps something is wrong in my configuration?
