stylesheet() does not enforce NestedCSSProperties type on record keys

[alexmoore0]

The stylesheet() function does not enforce NestedCSSProperties as keys on the child objects within the argument. This vastly reduces the usability of the stylesheet() function, as compared to the strict types enforced by style().

This code compiles just fine:

const styles = stylesheet({
  item: {
    borderLeft: "4px solid transparent",
    "this is a not a CSS property": "transparent",
  }
});

However, if I remove the borderLeft property, the TS compiler recognizes the invalid key.

It looks like the issue appears again - the workaround is to explicitly cast the object to a proper type, i.e.

const styles = stylesheet({
  item: {
    borderLeft: "4px solid transparent",
    "this is a not a CSS property": "transparent",
  }
} as Record<string, types.NestedCSSProperties>);
