Why is `opsz` doubled to `px` on Chromium and not on Webkit?

Variable fonts are supposed to have optical sizing proportionate to its px value automatically.

But it's not consistent in different browsers.

• if font-size: 16px
  • in Safari and Firefox – opsz: 16
  • in Chrome – opsz: 32

So I have to

body {
  font-variation-settings: "opsz" 16;
}

which is not automatic anymore, I have to redeclare every time I change font-size. Is it just me? Where should I start if I want to correct this?

Please see https://bugs.chromium.org/p/chromium/issues/detail?id=1305237 - there's been an issue with opsz depending on display resolution or zoom level. Aiming to release fix in Chrome 105 stable or already fixed in an up-to-date Chrome Canary.
