Bug 78875 – [v8] v8 doesn't assume to do 'new WebKitShadowRoot(host)'.

• Component: DOM
• Status: RESOLVED FIXED

[Shinya Kawanaka]

new WebKitShadowRoot(host) and internals.ensureShadowRoot(host) returns a different object now.
These should be the same, however they return different objects, which contain the same ShadowRoot object though.

The change looks OK, but the comment is confusing to me. Maybe you can just remove the comment.

Why "should" an ActiveDOMObject-and-DOMNode object be treated as DOMNode? In my understanding,
- There is no ActiveDOMObject-and-DOMNode object for now.
- If an ActiveDOMObject-and-DOMNode appeared in the future, we need another logic, like "setJSWrapperForActiveDOMNodeObject()".

Thanks. I've removed the comment.

platform/wk2/Skipped might be needed...? (I am not sure.)

Nit: This line is not necessary.

No one has added Skipped line for SHADOW_DOM there, but let's add this time for defensive style :-)

Thanks.

After fixing them, I'll land this.
