Describe the Bug

Experimental font api renders this

@font-face {
	  font-family: Nothing-7e874a521bb52888;
  src: url("/_astro/fonts/ffcca724dca7a641.otf") format(otf);
  font-display: swap;
  font-weight: 400;
  font-style: normal;
}
@font-face {
	  font-family: "Nothing-7e874a521bb52888 fallback: Courier New";
  src: local("Courier New");
  size-adjust: 82.3199%;
  ascent-override: 107.9325%;
  descent-override: 26.968%;
  line-gap-override: 0%;
}
:root { --ff-nothing: Nothing-7e874a521bb52888, "Nothing-7e874a521bb52888 fallback: Courier New", monospace; }

What's the expected result?

@font-face {
	  font-family: Nothing-7e874a521bb52888;
  src: url("/_astro/fonts/ffcca724dca7a641.otf") format("opentype");
  font-display: swap;
  font-weight: 400;
  font-style: normal;
}
@font-face {
	  font-family: "Nothing-7e874a521bb52888 fallback: Courier New";
  src: local("Courier New");
  size-adjust: 82.3199%;
  ascent-override: 107.9325%;
  descent-override: 26.968%;
  line-gap-override: 0%;
}
:root { --ff-nothing: Nothing-7e874a521bb52888, "Nothing-7e874a521bb52888 fallback: Courier New", monospace; }
