<h3>Log Message</h3>
<pre>Upgrading custom element should enqueue attributeChanged and connected callbacks
https://bugs.webkit.org/show_bug.cgi?id=163840

Reviewed by Darin Adler.

LayoutTests/imported/w3c:

Rebaselined the tests as more test cases are passing now.

* web-platform-tests/custom-elements/reactions/Node-expected.txt:
* web-platform-tests/custom-elements/reactions/Range-expected.txt:

Source/WebCore:

When upgrading a custom element, enqueue attributeChanged and connectedCallbacks as needed as specified
in step 3 and 4 of: https://html.spec.whatwg.org/multipage/scripting.html#concept-upgrade-an-element

Test: fast/custom-elements/upgrading-enqueue-reactions.html

* bindings/js/JSCustomElementInterface.cpp:
(WebCore::JSCustomElementInterface::upgradeElement): Enqueue
* dom/CustomElementReactionQueue.cpp:
(WebCore::CustomElementReactionQueueItem::invoke): Don't invoke callbacks when the custom element had
failed to upgrade.
(WebCore::CustomElementReactionQueue::enqueuePostUpgradeReactions): Added.
(WebCore::CustomElementReactionQueue::invokeAll): Upgrading a custom element may enqueue more reactions.
Keep invoking reactions until the queue becomes empty.
* dom/CustomElementReactionQueue.h:
* dom/Range.idl: Added a forgotten CEReactions here.

LayoutTests:

Added a W3C style testharness.js test for making sure upgrading custom custom elements
would enqueue attributedChanged and connected reactions.

* fast/custom-elements/upgrading-enqueue-reactions-expected.txt: Added.
* fast/custom-elements/upgrading-enqueue-reactions.html: Added.</pre>

+        Upgrading custom element should enqueue attributeChanged and connected callbacks
+        https://bugs.webkit.org/show_bug.cgi?id=163840
+
+        Reviewed by Darin Adler.
+
+        When upgrading a custom element, enqueue attributeChanged and connectedCallbacks as needed as specified
+        in step 3 and 4 of: https://html.spec.whatwg.org/multipage/scripting.html#concept-upgrade-an-element
+
+        Test: fast/custom-elements/upgrading-enqueue-reactions.html
+
+        * bindings/js/JSCustomElementInterface.cpp:
+        (WebCore::JSCustomElementInterface::upgradeElement): Enqueue 
+        * dom/CustomElementReactionQueue.cpp:
+        (WebCore::CustomElementReactionQueueItem::invoke): Don't invoke callbacks when the custom element had
+        failed to upgrade.
+        (WebCore::CustomElementReactionQueue::enqueuePostUpgradeReactions): Added.
+        (WebCore::CustomElementReactionQueue::invokeAll): Upgrading a custom element may enqueue more reactions.
+        Keep invoking reactions until the queue becomes empty.
+        * dom/CustomElementReactionQueue.h:
+        * dom/Range.idl: Added a forgotten CEReactions here.
