convert htmlcollection to simple array

[mogafk]

(sorry bad english)
i have strange behavior tinycon library. setBubble method changed favicon only after third call, probably because i have multiple favicons with different sizes.

    <link rel="icon" type="image/png" href="http://localhost:8080//s/favicon/favicon-196x196.png" sizes="196x196">
    <link rel="icon" type="image/png" href="http://localhost:8080//s/favicon/favicon-96x96.png" sizes="96x96">
    <link rel="icon" type="image/png" href="http://localhost:8080//s/favicon/favicon-32x32.png" sizes="32x32">
    <link rel="icon" type="image/png" href="http://localhost:8080//s/favicon/favicon-16x16.png" sizes="16x16">
    <link rel="icon" type="image/png" href="http://localhost:8080//s/favicon/favicon-128.png" sizes="128x128">

after small investigation i realized that setBubble remove link tags by pieces. HTMLCollection is to blame for this.

this code (attention to comments):

  var removeFaviconTag = function(){

    var links = document.getElementsByTagName('link');
    // links is HTMLCollection

    for(var i=0, len=links.length; i < len; i++) {
      var exists = (typeof(links[i]) !== 'undefined');
      if (exists && (links[i].getAttribute('rel') || '').match(/\bicon\b/i)) {
        links[i].parentNode.removeChild(links[i]);
        // after removeChild links length stay less by 1
        // but loop does not handle this
      }
    }
  };

Imagine that divs in demo it link tags
