Steps to Reproduce:

1. Create a JavaScript File with this content (the variable c99 is used to wrap the Game class in its own namespace, a common pattern in JavaScript):

var c99 = {};

c99.Game = (function () {
    function Count99Game() {
        console.log('Count99 game starts.');
        this.initGame();
    }

    Count99Game.prototype.initGame = function () {
        this.nextCountLabel = document.getElementById('next-count');
    };

    return Count99Game;
})();

2. Right-click on the "initGame" function on line 6 and choose "Go to Definition". Nothing happens. Expected behavior: The cursor should be positioned on line 9 where the function is defined. Works in NetBeans, for example.

Seems to be same root cause as #16489

Partially fixed by #21974. this assignments in nested functions are not tracked correctly still.

This example now seems to be working for me (shown by the references code lens):
