Fix `as` prop is not forwarded to target Component

[lesha1201]

Fixes: https://github.com/modulz/stitches/issues/979

Previous behaviour:

const StyledButton = styled('button', {
  color: 'red',
})

const Button = (props) => {
  return React.createElement(StyledButton, props)
}

const CustomStyledButton = styled(Button, {
  backgroundColor: 'blue',
})

// Renders: <Button {...} />
<CustomStyledButton />
// Renders: <a {...} />
<CustomStyledButton as="a" />

New behaviour:

const StyledButton = styled('button', {
  color: 'red',
})

const Button = (props) => {
  return React.createElement(StyledButton, props)
}

const CustomStyledButton = styled(Button, {
  backgroundColor: 'blue',
})

// Renders: <Button {...} />
<CustomStyledButton />
// Renders: <Button as="a" {...} />
<CustomStyledButton as="a" />

Do we have any plans to merge this? In general there are a few 0PRs worth merging. Anyone from the 🧵 team?

Hey everyone!

This change is no longer needed after the changes that we added in https://github.com/stitchesjs/stitches/pull/1103 which allow you to control how Stitches should handle its props like as,css or any Stitches defined variant.

Once this is released you should be able to manually override whether Stitches should handle the as prop or not:

const { styled } = createStitches()

const StyledButton = styled('button', {
  color: 'red',
})

const Button = (props) => {
  return React.createElement(StyledButton, props)
}

const forwardAsPropConfig = {
  shouldForwardStitchesProp: (prop) => {
    if (prop === 'as') {
      return true
    }
  },
}

const StitchesComponent = styled.withConfig(forwardAsProp)(Button, {})

The changes are merged with canary and will be released as a beta soon.
