Describe the Bug

When loading a Google font (specifically Recursive) with the variableAxis setting, the developer server will 404 trying to use it. The command line will 404 with

[404] /_astro/fonts/font-recursive-300-1000-oblique 0deg 15deg-latin-b700bf46346f99e2.woff2

and the in-browser console errors with

downloadable font: download failed (font-family: "Recursive-6fbe16cb0b76ff6a" style:normal weight:300..1000 stretch:100 src index:0): status=2147746065 source: http://localhost:4321/_astro/fonts/font-recursive-300-1000-oblique%200deg%2015deg-latin-b700bf46346f99e2.woff2

However, the font was fetched correctly; if I were to look in the /.astro/fonts directory, I can see the font file font-recursive-300-1000-oblique 0deg 15deg-latin-b700bf46346f99e2.woff2, which, if moved to /public/ and manually pointed to in my CSS, functions just like any other .woff2 font file would.

Steps to Reproduce

1. Configure astro.config.mjs with the following, and set the relevant <Font cssVariable="--font-recursive" /> component on a .astro file:

// @ts-check
import { defineConfig, fontProviders } from 'astro/config';

export default defineConfig({
  fonts: [
    {
      provider: fontProviders.google(),
      name: 'Recursive',
      cssVariable: '--font-recursive',
      weights: ['300 1000'],
      styles: ['normal', 'oblique'],
      options: {
        experimental: {
          variableAxis: {
            slnt: [['-15', '0']],
            CASL: [['0', '1']],
            CRSV: [['0', '1']],
            MONO: [['0', '1']],
          },
        },
      },
    },
  ],
});

2. Run astro dev, and attempt to load a page with the font.

3. Confirm font file exists in /.astro/fonts.

What's the expected result?

The font should load as-is, since it has been successfully downloaded and cached.
