"One thing to pay attention to when preloading fonts is that you also have to set the crossorigin attribute even if the font is on the same domain: <link rel="preload" href="font.woff" as="font" crossorigin>"

But why?

[the8472]

Because the spec says font-loads from stylesheets must always be anonymous CORS. Thus the preload needs to match that.
