Re: [csswg-drafts] [css-conditionals-5] Test for the support of a property name (#11159)

How to evaluate [support](https://drafts.csswg.org/css-conditional-3/#dfn-support) is indeed two parts:

  > If a processor does not implement, with a usable level of support, both the property and the value given, then it must not accept the declaration or claim support for it.

I assume *full support* means *parseable + usable*.

Closing as question answered... but the CSSWG resolved on adding `at-rule(@keyword)`, which seems similar, so I will keep an eye on how it should be evaluated, and possibly re-open this issue if necessary.
