Firefox SVG rendering

is crashing because of 'probably' this bug: https://bugzilla.mozilla.org/show_bug.cgi?id=700533

'''
source.onload = function () {
renderCanvasContext.drawImage(source, 0, 0, renderCanvas.width, renderCanvas.height);

        // place fill bitmap into svg
        var fillBitmap = renderCanvas.toDataURL("image/png");
        if(typeof callback === 'function'){
            callback(fillBitmap);
        }
        renderCanvas.remove();
    };

    // catch browsers without native svg support
    source.onerror = function() {
        console.error("Can't export! Maybe your browser doesn't support native SVG. Sorry.");
    };
};

'''
is running into the onerror case.

TODO: check if svg width and height is properly set and read the bug report for possible workarounds.
