           Summary: Shadow DOM throws WRONG_DOCUMENT_ERR
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org

We are killing WRONG_DOCUMENT_ERR across the web platform. The only places WebKit still fires this event are in DOM Ranges and in shadow DOM's validation after http://trac.webkit.org/changeset/90026. The correct thing to do if the shadowRoot's document is different than the one it's being set to is to do the adoptNode.

See ContainerNode::insertBefore for an example. I believe it's the setTreeScopeRecursively call that does it.
