Web Compatibility Support • Re: One Minor and One Major Issue at Intel website ( https://www.intel.com/content/www/us/en/homepage.html )

The minor issue is due to CSS :has not being supported, so the background doesn't get set. The major issue is because :not(:defined) is not a valid selector, causing a syntax error in loading the module; I also had to polyfill Intl.supportedValuesOf. However, then there was an error that Promise.withResolvers is not a function, and that's when I gave up.
