Salsa does not highlight object properties across methods

[alexdima]

Testing #2218

When I hover over this.age in the console.log I get to see it is a property of type number, but the assignment in line 2 is not highlighted:

function Person() {
    this.age = 13;
}
Person.prototype.sayHi = function() {
    console.log('Hi, I\'m ' + this.age);
    console.log('Hi, I\'m ' + this.age);
}

var p1 = new Person();
