// So that font loading (@font-face in CSS and FontFace.load()) always sends request
|
|
// with anonymous-mode CORS. The crossOrigin attribute of <link rel="preload" as="font">
|
|
// should be set as anonymout mode, too, even for same origin fetch. Otherwise,
|
|
// main font loading doesn't match the corresponding preloading due to credentials
|
|
// mode mismatch and the main font loading invokes another request.
