css.properties.font-synthesis - font-synthesis: none doesn't work on Chrome

What type of issue is this?

Incorrect support data

What information was incorrect, unhelpful, or incomplete?

Using font-synthesis: none; should prevent the browser from generating faux-italic fonts, but this doesn't work in Chromium.

It works fine in Safari and Firefox

What browsers does this problem apply to, if applicable?

Chromium (Chrome, Edge 79+, Opera, Samsung Internet)

What did you expect to see?

Regular fonts, not synthesised faux-italic ones.

Did you test this? If so, how?

Yes. Edit the css on the title on https://fonts.google.com/knowledge/glossary/faux_fake_pseudo_synthesized which doesn't have italic glyphs.

Safari and Firefox will honor the following, while Chromium will not.

{
	font-style: italic;
	font-synthesis: none;
}

MDN metadata

Start with the css.properties.font-synthesis entry and compare its Chromium compatibility data with the reproduction on the Google Fonts page. Review Chromium bug 1416834 and the linked MDN page for the expected behavior. Done means the compatibility data accurately reflects Chromium's handling of font-synthesis: none.
