iPhone X safe-area-inset error

[Jay Contonio]

Following the examples from Apple's documentation, v1.5.1 will throw an error for the following:

@supports(padding: max(0px)) {
    padding-left: max($marginWidth, env(safe-area-inset-left));
    padding-right: max($marginWidth, env(safe-area-inset-right));
  }

The error: "env(safe-area-inset-left)" is not a number for max'`
