Does not render data url

[hunterlester]

I'm able to create a data url and render it as an img tag source:

const reader = new FileReader();
reader.onload = () => {
    const url = reader.result;
    const parEl = document.getElementById('codebox');
    const img = document.createElement('img');
    img.setAttribute('src', url);
    parEl.appendChild(img);
};
reader.readAsDataURL(new Blob([data.buffer], { type: "image/jpeg"}));

However, Peruse doesn't render data: URL's.
