font-variant-east-asian
◐matches Chrome on some values3 of 5 examples match Chromecss-fonts-4
Some of the examples match Chrome and some do not. The count beside the verdict says how many — 11 of 12 — and the values that differ are listed on the property page. It is neither a pass nor a failure, and filing it under either would be a lie in one direction.
Here: 3 of 5 examples match Chrome. The 2 that do not: font-variant-east-asian:proportional-width, font-variant-east-asian:jis78 — shown first below, each with its difference map.

Which values were measured
“Supported” on one example means “supported at the value we tried”. The property’s declared grammar has 10 branches; 5 of them carry a measurement. The publishing ceiling is 12 examples per property — a branch past it is left out by our choice, not by accident.
