Playing sequence of videos on iPhone get stuck on fifth video everytime

Issue summary: I'm trying to play a sequence of youtube videos using the youtube iFrame api on iPhone (Only tested IOS8). I play the first loaded video by pressing the youtube play button, when i get the ended state i load the next video using loadVideoById. It works flawless for the first 4 videos but then the player get stuck in state 3 buffering and nothing happens. I have tried different youtube ids and and also using the same youtube id over and over again, but it allways get stuck on the fifth video.

Here is the code:

<script>
    var tag = document.createElement('script');

    tag.src = "http://ift.tt/18NYSmg";
    var firstScriptTag = document.getElementsByTagName('script')[0];
    firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

    var player;
    var videos = ["fWIBXhQrHE4", "hMo2ovaa8bc", "sOpuSRj7IN4", "fWIBXhQrHE4", "hMo2ovaa8bc", "sOpuSRj7IN4", "fWIBXhQrHE4", "hMo2ovaa8bc", "sOpuSRj7IN4", "fWIBXhQrHE4", "hMo2ovaa8bc", "sOpuSRj7IN4"];
    var currentVideo = 0;
    function onYouTubeIframeAPIReady() {
        player = new YT.Player('player', {
            height: '390',
            width: '640',
            videoId: videos[currentVideo],
            playerVars: {
                disablekb: 0
            },
            events: {
                'onReady': onPlayerReady,
                'onStateChange': onStateChange
            }
        });
    }

    function onStateChange(event) {
        console.log("state: " + event.data);
        switch(event.data){
            case YT.PlayerState.ENDED:
                loadNext();
                break;
        }
    }

    function loadNext() {
        if(currentVideo < videos.length-1){
            currentVideo++;
            console.log("currentVideo: " + currentVideo);
            player.loadVideoById(videos[currentVideo], 0, "hd720");
        }
        else{
            console.log("ALL DONE");
        }
    }

    function onPlayerReady(event) {
        //console.log("playerready");
        //event.target.playVideo();
    }
</script>

Steps to reproduce issue:

1. 
   

   Run this fiddle http://ift.tt/1HL0iTD or the attached code in safari on an iPhone with IOS 8.

   
   


2. 
   

   Press play on the youtube player.

   
   


3. When the video started in fullscreen press the next button to trigger the ended event, the player exits fullscreen loads the next video and opens fullscreen again.


4. Redo step 3 four times and the player get stuck in state 3 buffering.

Expected output: The player should play the loaded video.

Actual results: The player get stuck in state 3 buffering.
