Sometimes the FileReader does not response

@Dovel wrote:

Is there a known issue of the FileReader in Ionic? In my case the FileReader is sometimes not responding.

let obj = { hello: 'world' };
let json = JSON.stringify(obj, null, 2);
let blob = new Blob([json], { type: 'application/json' });

let readBlob = function (data) {

  let reader = new FileReader();

  reader.onload = () => {
    console.log('Loaded: ', reader.result);
  };

  reader.onerror = error => {
    console.log('Error: ', error);
  };

  reader.onabort = () => {
    console.log('Aborted');
  };

  reader.readAsText(data);

};

readBlob(blob);

I wrapped the code in try-catch and print every single step. Sometimes there is no reaction of the FileReader. No event is fired. No errors.
