HeroUI Version

Describe the bug

The extendVariants typing tells us that it is possible to pass a slots option to override each possible slot of the base component, but I am not able to override the label slot of the Input component.

Steps to Reproduce the Bug or Issue

CodeSandBox: https://codesandbox.io/p/devbox/nostalgic-jang-q9kw4r?file=%2Fapp%2Fpage.tsx%3A9%2C1

Inline Code:

import { Input as BaseInput } from "@heroui/input";
import { extendVariants } from "@heroui/system-rsc";

export const Input = extendVariants(BaseInput, {
  slots: {
    label: '!font-medium', // This style does not show, even with `!` (`!important`) specifier.
  },
});

export default function HomePage() {
  return (
    <Input label="My label" labelPlacement="outside-top" />
  );
}

Expected behavior

I believe it should be possible to override each component slot globally for all possible variants, where each variant in turn can override that slot.
