Message:

CSSStyleDeclaration should be annotated with CEReactions
​https://bugs.webkit.org/show_bug.cgi?id=163968

Reviewed by Antti Koivisto.

LayoutTests/imported/w3c:

Rebaselined the test now that all test cases pass.

• web-platform-tests/custom-elements/attribute-changed-callback-expected.txt:

Source/WebCore:

Added CEReactions to CSSStyleDeclaration.idl.

Test: fast/custom-elements/reactions/CSSStyleDeclaration.html

• bindings/js/JSCSSStyleDeclarationCustom.cpp:

(WebCore::JSCSSStyleDeclaration::putDelegate):

• css/CSSStyleDeclaration.idl:
• css/PropertySetCSSStyleDeclaration.cpp:

(WebCore::StyleAttributeMutationScope::StyleAttributeMutationScope): Remember the old value when this is
an inline style declaration for a custom element. Also store m_oldValue and m_customElement instead of
a mutation record so that we don't create a superfluous mutation record for custom elements.
(WebCore::StyleAttributeMutationScope::~StyleAttributeMutationScope): Enqueue attributeChangedCallback
when m_customElement is not null.

• dom/CustomElementReactionQueue.cpp:

(WebCore::CustomElementReactionQueue::observesStyleAttribute):

• dom/CustomElementReactionQueue.h:

LayoutTests:

Added a W3C style testharness.js test.

• fast/custom-elements/reactions/CSSStyleDeclaration-expected.txt: Added.
• fast/custom-elements/reactions/CSSStyleDeclaration.html: Added.
