The following is just an observation and me asking out of curiosity, not a big deal:

Normally I throw an error here to help users understand what's going on. In the case you described in the PR description can't you remove the babel plugin altogether so that style tags are not turned into JSXStyle elements?

In certain use cases, for example a lib that renders a component (which has styled-jsx inside) with renderToStaticMarkup. We can't throw since it should not block rendering, and we can't ask them to disable the babel plugin as well because it's not a project level thing.

}

if (typeof window === 'undefined') {
registry.add(props)
return null
}

useLayoutEffect(() => {
registry.add(props)
return () => {
registry.remove(props)
}
// props.children can be string[], will be striped since id is identical
}, [props.id, String(props.dynamic)])

return null
}
