Wrong generated values for 'Rubik' and 'Inconsolata' (backup: 'Arial')

🐛 The bug

The line heights seem to be correct, but the character widths are wrong. I'm also using Roboto as a backup for android, but haven't checked it yet. I'm too lazy to make a stackblitz repro, here are the generated values:

@font-face {
  font-family: 'Rubik';
  src: url('/fonts/Rubik.ttf') format('truetype');
  font-display: swap;
}
@font-face {
  font-family: 'Rubik fallback';
  src: local('Arial');
  size-adjust: 104.9796%;
  ascent-override: 89.0649%;
  descent-override: 23.8141%;
  line-gap-override: 0%;
}

@font-face {
  font-family: 'Inconsolata';
  src: url('/fonts/Inconsolata.ttf') format('truetype');
  font-display: swap;
}
@font-face {
  font-family: 'Inconsolata fallback';
  src: local('Arial');
  size-adjust: 112.1577%;
  ascent-override: 76.5886%;
  descent-override: 16.9404%;
  line-gap-override: 0%;
}
