Created attachment 467589 [details] Oblique angle test shown in Safari 16.6 on the left and Firefox 117.0 on the right Using the `oblique` value with a specific angle for the `font-style` property does not work as expected when the font style is synthesized. Instead of slanting the font according to the specified angle, the value behaves more like a binary toggle: For anything under 14 degrees, no slanting is applied. For anything over 14 degress, the default of 14 degrees is applied (even if the specified angle is much higher). Here is a test page on CodePen: https://codepen.io/NickSherman/pen/oNJBeRv See comparison of Safari 16.6 vs Firefox 117.0 attached.
