Serialized SVG image with base64 embedded font, not rendering correctly in IE Edge

问题

Edit: Issue reported to microsoft

I have a inline svg element with a custom font that is embedded as a base64 string (.woff format).

Using javscript, I am serializing the SVG element and using it as a source for an img element. Jsbin Link

var svg = document.querySelector('svg');
var svgData = new XMLSerializer().serializeToString(svg);
var img = document.createElement("img");
img.setAttribute("src", "data:image/svg+xml;base64," + btoa(svgData));
document.body.appendChild(img);

svg { width: 400px; max-width:calc(100% - 100px); height: auto; }
img { width: 400px; max-width:calc(100% - 100px); height: auto; }

The custom font renders correctly in Chrome, Firefox, IE 11 but not in Edge.

Have I missed something? What should I do to make the custom font render properly in Edge?
