loadImage(imgUrl,img => {
    document.body.appendChild(img);
  },
  {
    maxWidth: 750,
    orientation: true,
    canvas: true
  })

the code above will throw a network error on iOS 9

XMLHttpRequest Exception 101: A network error occurred in synchronous requests

my temporary solution is replacing loadImage.fetchBlob with the function below

loadImage.fetchBlob = function (url, callback, options) {
  function executor(resolve, reject) {
    var img = new Image();
    img.src = url;
    img.onload = function () {
      var c = document.createElement('canvas');
      c.width = img.width;
      c.height = img.height;
      var ctx = c.getContext('2d');
      ctx.drawImage(img, 0, 0);
      c.toBlob(bin => {
        resolve(bin);
      });
    };
    img.onerror = function() {
      reject(Error('load image fail'))
    }
  }
  if (global.Promise && typeof callback !== 'function') {
    options = callback; // eslint-disable-line no-param-reassign
    return new Promise(executor);
  }
  return executor(callback, callback);
};

Thanks for your report @littlee. Unfortunately I don't have a access to a iOS 9 test device (and it seems simulator runtimes are only available down to iOS 11 for me). Is this issue limited to iOS9 or does it also occur in other versions?
