I have a demo here: https://codepen.io/Jsbbvk/pen/KKXNPYO

var canvas = new fabric.Canvas("canvas");

const text = new fabric.IText("sample text")
text.set({
  fontFamily: "Impact",
  left: (this.canvas.width - text.width) / 2,
  top: (this.canvas.height - text.height) / 2,
})
canvas.add(text)
canvas.requestRenderAll()

If you visit this codepen on a mobile device, you'll see that the Impact font doesn't load. However, visiting this codepen on a desktop will work. Is there a fix to this?
