* LayoutTests/imported/w3c/web-platform-tests/css/css-contain/container-queries/custom-property-style-queries-expected.txt:
* Source/WebCore/css/query/ContainerQueryFeatures.cpp:

Resolve custom property values in style queries against the current style and registered property enviroment using Style::Builder.

* Source/WebCore/css/query/GenericMediaQueryParser.cpp:

Parse the custom property value in query using the path that returns unresolved and css-wide keyword values if needed.

(WebCore::MQ::consumeCustomPropertyValue):
* Source/WebCore/style/ContainerQueryEvaluator.cpp:

Pass also the parent style so 'inherit' can be resolved correctly.

(WebCore::Style::ContainerQueryEvaluator::featureEvaluationContextForQuery const):
* Source/WebCore/style/StyleBuilder.cpp:
(WebCore::Style::Builder::resolveCustomPropertyForContainerQueries):

Expose a helper for this case.
