'auto' keyword parsing in font descriptors inside @font-face rule

According to spec https://www.w3.org/TR/css-fonts-4/#font-prop-desc the 'auto' keyword for 'font-weight', 'font-style' and 'font-stretch' descriptors inside @fotn-face rule should be supported, Safari however does not support parsing of 'auto' keyword. 

So in the attached html file, the expected result is that you should see "Font weight range: auto" in the browser, however in Safari it is "Font weight range:".

Corresponding WPT tests *'auto' keyword inside @font-face: auto* in https://wpt.fyi/results/css/css-fonts/variations/at-font-face-descriptors.html?label=experimental&label=master&aligned are also not passing in Safari.
