'material ui 'new' v5.0.0 injectFirst fails to set specificity

MUI v5.0.0 was released today and in my spike branch I am attempting to update to the new version. I'm working through the steps in the mui-docs detailed here. I am using styled-components with NextJS and it seems that the mui-styles are not injecting first. I'm not sure what I can do differently to get ahead of this, afaik I've been following everything correctly in that guide and making changes incrementally. Yet, I'm still having the specificity bug.

styled-component's style below everything else.

<StylesProvider injectFirst> doesn't seem to work correctly now

Thoughts?

_app.tsx

import styled, { createGlobalStyle, ThemeProvider } from 'styled-components';
import withDarkMode, { useDarkMode } from 'next-dark-mode';
import defaultTheme from 'src/theme';
import TopNavigation from '@components/_molecules/TopNavigation/TopNavigation';
import StyledTypography from '@components/_atoms/Typography/StyledTypography';
import { Provider } from 'react-redux';
import { StylesProvider } from '@mui/styles';

function MyApp({ Component, pageProps }): JSX.Element {

  // ? https://nextjs.org/docs/basic-features/layouts
  const getLayout = Component.getLayout || (page => page);

  return (
    <StylesProvider injectFirst>
      <ThemeProvider theme={setTheme}>
        <RootStyles>
            <PageLayout>
              <TopNavigation />
              <Body>
                {getLayout(
                  <Provider store={store}>
                    <Component {...pageProps} />
                  </Provider>
                )}
              </Body>
              <Footer />
            </PageLayout>
        </RootStyles>
      </ThemeProvider>
    </StylesProvider>
  );
}

const RootStyles = styled.div`
  color: ${({ theme }) => theme.palette.font.primary};
`;

_document.js

import Document, { Html, Head, Main, NextScript } from 'next/document';
import { ServerStyleSheet } from 'styled-components';
import { ServerStyleSheets } from '@mui/styles';

class MyDocument extends Document {
  static async getInitialProps(ctx) {
    const styledComponentsSheet = new ServerStyleSheet();
    const materialSheets = new ServerStyleSheets();
    const originalRenderPage = ctx.renderPage;

    try {
      ctx.renderPage = () =>
        originalRenderPage({
          enhanceApp: App => props =>
            styledComponentsSheet.collectStyles(
              materialSheets.collect(<App {...props} />)
            ),
        });

      const initialProps = await Document.getInitialProps(ctx);

      return {
        ...initialProps,
        styles: (
          <>
            {initialProps.styles}
            {materialSheets.getStyleElement()}
            {styledComponentsSheet.getStyleElement()}
          </>
        ),
      };
    } finally {
      styledComponentsSheet.seal();
    }
  }

  // eslint-disable-next-line @typescript-eslint/explicit-module-boundary-types
  render() {
    return (
      <Html lang="en" dir="ltr">
        <Head>
          <link rel="preconnect" href="https://fonts.gstatic.com" />
          <link
            rel="stylesheet"
            href="https://fonts.googleapis.com/css2?family=Poppins:wght@300;400;500;600&display=swap"

        <body>
          <Main />
          <NextScript />
        </body>
      </Html>
    );
  }
}

export default MyDocument;

Try this

import StyledEngineProvider from '@mui/material/StyledEngineProvider';

function App() {
  return (
    <StyledEngineProvider injectFirst>
      <OtherComponents />
    </StyledEngineProvider>
  );
}
