Source/WebCore:
::after and ::before don't work on :host
https://bugs.webkit.org/show_bug.cgi?id=164675
<rdar://problem/29231874>
Reviewed by Andreas Kling.
We didn't allow combining :host with any other selectors. Pseudo elements should be allowed.
Test: fast/shadow-dom/shadow-host-with-before-after.html
* css/ElementRuleCollector.cpp:
(WebCore::ElementRuleCollector::matchAuthorRules):
Allow pseudo element matching.
(WebCore::ElementRuleCollector::matchHostPseudoClassRules):
Use the normal collectMatchingRulesForList path instead of a direct call to SelectorChecker::matchHostPseudoClass.
This path supports pseudo elements.
Pass the information that we are matching :host rules with m_isMatchingHostPseudoClass bit
similarly to how this is done with slots.
(WebCore::ElementRuleCollector::ruleMatches):
* css/ElementRuleCollector.h:
* css/RuleSet.cpp:
Collect :host rules similarly to other rules.
(WebCore::RuleSet::addRule):
* css/SelectorChecker.cpp:
Rename didMoveToShadowHost->mayMatchHostPseudoClass for clarity.
(WebCore::SelectorChecker::match):
Enable :host matching in the current context immediately if needed.
(WebCore::SelectorChecker::matchHostPseudoClass):
The check for illegal combinations with :host is now done in checkOne().
(WebCore::localContextForParent):
(WebCore::SelectorChecker::checkOne):
In context where :host matches nothing else can match, except pseudo elements.
