<h3>Log Message</h3>
<pre>Add :defined support
https://bugs.webkit.org/show_bug.cgi?id=155108
Reviewed by Antti Koivisto.
Source/WebCore:
Added :defined pseudo class which applies to a successfully instantiated custom element or a builtin element.
A new node flag, isUnresolvedCustomElement, which was added in <a href="http://trac.webkit.org/projects/webkit/changeset/197917">r197917</a> tracks un-upgraded / unresolved custom
elements for which :defined should not apply.
Tests: fast/custom-elements/defined-pseudo-class.html
fast/custom-elements/defined-rule.html
* bindings/js/JSCustomElementInterface.cpp:
(WebCore::JSCustomElementInterface::constructElement): Unset isUnresolvedCustomElement now that HTMLElement's
constructor sets isUnresolvedCustomElement.
* bindings/js/JSHTMLElementCustom.cpp:
(WebCore::constructJSHTMLElement): Set isUnresolvedCustomElement to true since :defined should never apply to
a custom element inside its constructor as HTMLElement constructor does not set the defined flag:
https://w3c.github.io/webcomponents/spec/custom/#htmlelement-constructor
* css/CSSSelector.cpp:
(WebCore::CSSSelector::selectorText): Added the support for serializing :defined.
* css/CSSSelector.h:
(PseudoClassType): Added PseudoClassDefined for :defined.
* css/SelectorChecker.cpp:
(WebCore::SelectorChecker::checkOne): Added the support for :defined.
* css/SelectorCheckerTestFunctions.h:
(WebCore::isDefinedElement): Added. Returns true for any builtin element and a custom element after a successful
construction / upgrades.
* css/SelectorPseudoClassAndCompatibilityElementMap.in: Added :defined.
* cssjit/SelectorCompiler.cpp:
(WebCore::SelectorCompiler::addPseudoClassType): Added the support for :defined.
LayoutTests:
Added W3C style testharness.js tests and ref tests for :defined pseudo class.
* fast/custom-elements/defined-pseudo-class-expected.txt: Added.
* fast/custom-elements/defined-pseudo-class.html: Added.
* fast/custom-elements/defined-rule-expected.html: Added.
* fast/custom-elements/defined-rule.html: Added.</pre>
