TypeScript Variants Type Information Lost When Extending

[ryanelian]

Describe the bug

variants declared in a variant is not carried over to subsequent variants when extended.

Before I get chastised for doing this, I want to let everyone know that the reason I'm doing this is because Tailwind VS Code Intellisense breaks down and stop working when your variant gets too big, and I don't know how to fix it.

To Reproduce

Steps to reproduce the behavior:

import { VariantProps, tv } from 'tailwind-variants';

export const buttonBaseVariants = tv({
  base: '',
  variants: {
    mode: {
      contained: '',
      text: '',
    },
  },
});

export const buttonIntentVariants = tv({
  extend: buttonBaseVariants,
  variants: {
    intent: {
      primary: '',
      secondary: '',
      danger: '',
    },
  },
});

export const buttonVariants = tv({
  extend: buttonIntentVariants,
  variants: {
    size: {
      small: '',
      medium: '',
      large: '',
    },
  },
});

Expected behavior I expect the final function to contain the variants extended from the original and subsequent variants. Note below that mode is missing from the type information:
