Looks like :not() isn't supported

Hey there, I'm finding a problem with treeshaking working with Tailwinds spacing classes. It looks like Tailwind outputs this

.space-y-0 > *:not(template) ~ *:not(template) {/* some css */}

I'm getting this php error from it

Fatal error: Uncaught Symfony\Component\CssSelector\Exception\SyntaxErrorException: Expected selector, but <eof at 12> found. in /var/www/html/wp-content/themes/adk-fusion-360-wordpress-theme-2020/vendor/symfony/css-selector/Exception/SyntaxErrorException.php:33

Seems yes, will add a test case and then trying to fix it.

That's fantastic thank you!

@devboldium I have an issue with testing it. Probably can you provide a minimal HTML (with such inline css) ?
It also would be good to know you PHP version.

Hey @kala4ek , sorry this took so long,

<style>
.not-first-red > *:not(template) + *:not(template) {
  color: red;
}
</style>
<ul class="not-first-red">
  <li>Lorem ipsum dolor sit amet.</li>
  <li>Iste quos obcaecati alias neque.</li>
  <li>Cumque dicta vitae officiis ea.</li>
  <li>Quasi placeat voluptatem eius maxime.</li>
  <li>Aspernatur, soluta explicabo? Iste, dignissimos!</li>
</ul>

here's a codepen example
