fontWeight and fontFamily not applied on breakpoints in Gluestack UI

[MrLapa]

Description

fontWeight & fontFamily styles not being applied when using breakpoints in custom components

Steps to reproduce

When implementing custom components with breakpoint-specific styles in Gluestack UI, the fontWeight and fontFamily styles are not properly applied under breakpoint conditions. This inconsistency affects styling across various viewport sizes. Notably, other styles like fontSize and lineHeight work as expected and are correctly applied at different breakpoints.

Heading component code:

Heading.tsx

import { H1, H2, H3, H4, H5, H6 } from "@expo/html-elements"
import React from "react"

import { GluestackHeading } from "./Heading.styles"

import { type IHeadingProps } from "@/modules/eve"

const sizeToElement = {
  h1: H1,
  h2: H2,
  h3: H3,
  h4: H4,
  h5: H5,
  h6: H6,
}

export const Heading: React.FunctionComponent<IHeadingProps> = ({
  children,
  ...props
}) => {
  return (
    <GluestackHeading as={sizeToElement[props.size]} {...props}>
      {children}
    </GluestackHeading>
  )
}

export default Heading

const components = createComponents(componentsTheme)

export const theme = {
  config,
  components,
}

Steps to Reproduce:

1. Use the following configuration for the Heading component:

import { createStyle } from "@gluestack-style/react";

export const Heading = createStyle({
  variants: {
    size: {
      h1: {
        "fontFamily": "$body",
        "fontSize": "$xl",
        "lineHeight": "$xl",
        "fontWeight": "$semibold",
        "@md": {
          fontFamily: "$heading",
          fontSize: "$2xl",
          lineHeight: "$2xl",
          fontWeight: "$bold",
        },
      },
      h2: {
        "fontFamily": "$body",
        "fontSize": "$xl",
        "lineHeight": "$xl",
        "fontWeight": "$semibold",
        "@md": {
          fontFamily: "$heading",
          fontWeight: "$bold",
        },
      },
      // Other heading levels...
    },
  },
});

2. Apply the Heading component to a React component:

<Heading size="h1">Responsive Heading</Heading>

3. Resize the browser window to test responsiveness.

Expected Behavior

The styles under the @md breakpoint should be applied when the browser width meets the defined breakpoint.

Actual Behavior

The styles defined under the @md breakpoint are not applied. Instead, only the base styles are reflected, regardless of the viewport size.
