Salsa does not use JSDoc all the way in type inference

Testing #2218

I would expect Person and Person2 to behave the same given the JSDoc "types" age to be a number.

/**
 * @param {number} age
 */
function Person(age) {
    this.age = age; // <- it knows age is a number
}

function Person2() {
    this.age = 13;
}

var p1 = new Person();
var p2 = new Person2();

var a = p1.age; // <- it doesn't know this is a number
var b = p2.age; // <- it knows this is a number
