The above border and space-x utilities will not render correctly in FireFox. Currently, Tailwind v4 uses the Houdini APIs' @property syntax which is not supported in release versions of FireFox.

        @property --tw-space-x-reverse {
          syntax: "";
          inherits: false;
          initial-value: 0;
        }
        @property --tw-border-style {
          syntax: "";
          inherits: false;
          initial-value: solid;
        }
