Calme1709 has just submitted a new pull request for https://github.com/w3c/csswg-drafts: == [css-mixins-1] Make defaultValue member of FunctionParameter non-nullable == This is already optional so there's no need to have it nullable as well. This matches the [behavior of Chrome](https://source.chromium.org/chromium/chromium/src/+/main:third_party/blink/renderer/core/css/css_function_rule.idl;l=8) (the only implementer at time of writing) and matches the [behavior expected by WPT](https://github.com/web-platform-tests/wpt/blob/3db1450c66f9e44c5ebfe825e43d39a850a154fa/css/css-mixins/at-function-cssom.html#L242) (note that a missing `defaultValue` is undefined in the returned object, rather than `null`) See https://github.com/w3c/csswg-drafts/pull/13604 -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
