### Additional Information

Hi! I'm working with Native Base Button variants, creating new Link variant, but padding modify only works if it pass through component like this.
```js

{!loading ? text : }

```

```
{}} />
```
```
const variantLink = (props: Dict) => {
const c = props?.theme?.colors

return {
bg: 'none',
width: 'auto',
px: 0,
py: 0,
_text: {
color: c?.green?.main,
fontWeight: 700
}
}
}

export const buttonVariants = {
primary: variantPrimary,
link: variantLink
}
```

But if I remove px and py and include it in variant as codesandbox below, padding still appears (like screenshot)
