Styles are missing when using next.js 13's app folder

[victorteokw]

Hi,

Thanks for this great package. 🎉 This has been working well with next.js 11 and 12. But when I migrate the project to next.js 13 with app folder, styles are missing. There aren't style tags inserted into head.

See this vercel/next.js#41745
