            Bug ID: 154594
           Summary: new Range().createContextualFragment() throws DOM
                    Exception 9
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: russell at besworks.net

After creating a Range object using the constructor the createContextualFragment method throws DOM Exception 9 rather than returning a DocumentFragment object as expected.

If Range.setStart and Range.setEnd are called to set the Range's boundaries then createContextualFragment works as expected.

Looking at Range.cpp I can see that createContextualFragment checks if startContainer is an HTMLElement but the Range constructor sets startContainer as the global document object which is an HTMLDocument and therefore fails this check.
