Snap.svg load external svg file doesn't show properly in Firefox

I try to import old project written in Emberjs to new angular2 project. In emberjs my previous mate was loading external svg file like this:

<object id="svgobj" class="scaling-svg" data="/images/monitor.svg?v=3"
        type="image/svg+xml"></object>

And then in JS

this.$('#svgobj')[0].addEventListener('load', function() {
      _snap = Snap("#svgobj");  
      self.registerCpuUsageControllerEvent();
      svgTooltip(_snap);
      self.go();
    });

I didn't like this way and I tried to load svg like this:

<div id="svgobj" class="scaling-svg"></div>

JS:

Snap.load("/images/monitor.svg", (loadedFragment => {
            $("#svgobj").append(loadedFragment.node);
            this._snap = new Snap("#svgobj svg");
            this.svgObj = true;
            this.start();
        }));

But now it doesn't work in Firefox.. Two screenshots below.
