Description

Hello!

I am not sure if what I'm about to describe is Next.js bug or react-jss's, but here we go:

Describe the bug: I'm trying to use react-jss with Next.js as described in Next.js official example. However if I try to use it with Next.js amp build configuration, amp-custom attribute gets striped from the <style> element.

I've created issue about it here: https://github.com/zeit/next.js/issues/12243.

Expected behavior: amp-custom attribute should not get striped from <style> tag in <head>.

Codesandbox link: As the issue is connected to Next.js, I couldn't really create a Sandbox link. Instead I've created repository with 2 Next.js projects (and different implementations of react-jss). Repo is here: Repo is here: https://github.com/cibulka/nextjs-amp-jss

Versions (please complete the following information):

  • jss: 10.1.1
  • Browser: Chrome
  • OS: macOS (10.15.4)

I'm only just starting with AMP, so I might be missing something obvious. Thank you!

Research direction
Investigate how Next.js handles <style> tags during AMP rendering. Check the Next.js issue #12243 for similar reports. Examine the JSS output to see if the 'amp custom' attribute is present before Next.js processes the HTML. Consider looking at how react jss injects styles and whether the attribute is lost in the DOM or during serialization.
