LayoutTests/imported/w3c/web-platform-tests/css/selectors/invalidation/has-sibling-insertion-removal-expected.txt:
* Source/WebCore/style/ChildChangeInvalidation.cpp:
(WebCore::Style::isSiblingHasRelation):
(WebCore::Style::ChildChangeInvalidation::invalidateForChangedElement):
Optimization that tries to detect that :has() state doesn't change does not work
with sibling combinators. Don't use it in this case.
* Source/WebCore/style/RuleFeature.cpp:
(WebCore::Style::isSiblingCombinator):
(WebCore::Style::isHasScopeBreakingCombinator):
(WebCore::Style::RuleFeatureSet::recursivelyCollectFeaturesFromSelector):
Besides the subject selector also collect :has() invalidation selectors for
compounds that start a sibling combinator.
Sibling changes can affect elements in subtrees that are not part of the
mutation.
Reorganize and simplify the code.
(WebCore::Style::RuleFeatureSet::collectFeatures):
