Twitch player events won't fire with Vue?

The problem appears to be something to do with Vue creating it’s own virtual DOM. To fix it, initialize the twitch player within a method inside of vue.

const v = new Vue({
  el: "#app",
  methods: {
    init: function() {
      var options = {
        width: 400,
        height: 300,
        channel: "twitchpresents"
      }
      var player = new Twitch.Player("SamplePlayerDivID", options);

      player.addEventListener(Twitch.Player.READY, () => {
        alert("Player is ready!!");
      });
    }
  },
  mounted: function() {
    this.init();
  }
});
