CSS `content` property no longer renders encoded characters

Do you want to request a feature or report a bug?

bug

What is the current behavior?

Old behavior now must be done through string-literal instead of standard string.

If the current behavior is a bug, please provide the steps to reproduce and possibly a minimal demo or testcase in the form of a Next.js app, CodeSandbox URL or similar

The following no longer works in NextJS 9.1.1 to render a encoded character:

<style jsx>{`
.whatever-class:after { content: "\\0025B6"; };
</style>

We now have to do:

.whatever-class:after { content: ${`"\\0025B6"`}; }

What is the expected behavior?

Standard way of rendering content should still work.

Environment (include versions)

• OS: macOS Catalina
• Browser: Chrome 77
• styled-jsx (version): NextJS 9.1 bundled (styled-jsx@3.2.2)

Did this work in previous versions?

Yes
