-----------
Introduce an event when attaching a shadow root to an element
https://bugs.webkit.org/show_bug.cgi?id=299580
Reviewed by Sihui Liu.
Introduce a new DOM event, webkitshadowrootattached, which gets fired on an
element
whenever a non-user-agent shadow root attached to the element.
We dispatch this event whenever DOM wrapper world is supposed to have access to
all
shadow roots regardless of its mode.
Tests: Tools/TestWebKitAPI/Tests/WebKitCocoa/FormValidation.mm
Tools/TestWebKitAPI/Tests/WebKitCocoa/UserContentController.mm
* LayoutTests/fast/dom/gc-dom-tree-lifetime-shadow-tree.html: Fixed the test to
wait
with a 0s timer so that we perform the liveness check after
webkitshadowrootattached
has been dispatched.
