What minimal configuration is needed to reproduce the bug?

{
  "rules": {
    "property-no-unknown": true
  }
}

Do you have a proposal to fix the bug?

1. Add at-rule-descriptor-no-unknown #8148 should be completed
2. exceptions like
   

   stylelint/lib/rules/property-no-unknown/index.mjs

   Lines 26 to 27 in 4385d8f

   	// postcss doesn't distinguish between descriptors and properties
   	'navigation',

   
   should be removed
   i.e. decline property-no-unknown false positive for descriptor navigation #7751
3. an at-rule/descriptor map should be created for the descriptors that happen to be named after existing properties
4. the descriptors should be ignored
