IE10/11 can't execute blob-js with 114688 bytes size

gistfile1.js

var text = "var a = '";
for (var i = text.length; i < 114686; i++) {
    text += '1';
}
text += "';";
console.log('text size:', text.length);
var blob = new Blob([text], {type: 'text/javascript'});
var url = URL.createObjectURL(blob);

var script = document.createElement('script');
script.setAttribute('type', 'text/javascript');
script.setAttribute('charset', 'utf-8');

// no events for size 114688
script.onload = function() { console.log('onload'); };
script.onerror = function() { console.log('onerror'); };
script.onreadystatechange = function() { console.log('onreadystatechange'); };

script.setAttribute('src', url);

document.body.appendChild(script);
