Created attachment 406922 [details] test case, second paragraph is broken in safari Setting `font-variant-caps: small-caps` enables the display of small caps if available in an OpenType font (uppercase characters are still taller than lowercase ones, see first paragraph in attached example). (For spec see: https://developer.mozilla.org/en-US/docs/Web/CSS/font-variant-caps) Setting `font-variant-caps: all-small-caps` should also render "uppercase" characters as low as lowercase small caps (second paragraph). This works on Firefox and Chrome, but produces weird rendering in Safari, some lines are randomly very small (tested in Safari 13 on macOS 10.15 and iOS 13). When directly enabling the equivalent OpenType features (see third paragraph), it also works in Safari. Please fix `font-variant-caps: all-small-caps` so that second paragraph renders like third one!
