           Summary: [GTK] Fix iframe appended as child from DOM bindings
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit2
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: rego at igalia.com

The following code hangs in WebKit2GTK+ (in WK1 it works properly):

    WebKitDOMDocument* document;
    WebKitDOMHTMLElement* body;
    WebKitDOMElement* iframe;

    body = webkit_dom_document_get_body(document);

    iframe = webkit_dom_document_create_element(document, "iframe", NULL);
    webkit_dom_node_append_child(WEBKIT_DOM_NODE(body), WEBKIT_DOM_NODE(iframe), NULL);

The problem seems to be that when the new iframe is added, the WebProcess try to load it and it waits forever for the UIProcess in WebFrameLoaderClient::dispatchDecidePolicyForNavigationAction() when it uses Messages::WebPageProxy::DecidePolicyForNavigationAction().

It seems that there're some communication issues between the WebProcess and the UIProcess, beacause of the UIProcess is never notified in WebPageProxy::decidePolicyForNavigationAction().

WebProcess backtrace:
