Bug ID: 58802
           Summary: Inserting XML document fragment adds the fragment
                    instead of its content.
           Product: Wine
           Version: 9.0
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: msxml3
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

When MSXML's IXMLDOMDocumentFragment is inserted into the children of another
node, the fragment's content should be inserted rather than the fragment node
itself. When using Wine's MSXML3 implementation though, the fragment is
inserted into the XML DOM hierarchy.

As an example, inserting a fragment (represented here as an element with no
name) like this:
  <>
    <child2 />
  </>

At the end of an element's children:
  <root>
    <child1 />
  </root>

Should produce this XML:
  <root>
    <child1 />
    <child2 />
  </root>

But instead produces:
  <root>
    <child1 />
    <>
      <child2 />
    </>
  </root>

I first noticed this while diagnosing some test failures for HexEdit while
running under Wine 9.0, and then created a smaller reproduction of the issue.
- Reproduction code:
https://github.com/the-nerbs/wine-repros/tree/5f36fc0f493caf9972836f9630aae3...
- Built 32-bit repro exe:
https://github.com/the-nerbs/wine-repros/blob/5f36fc0f493caf9972836f9630aae3...
- Original application code: https://github.com/the-nerbs/HexEdit

The reproduction code exhibits the same issue when built as both 32 and 64 bit,
running under Wine 9.0. I have also reproduced the issue on a 32-bit build of a
fresh pull of the Wine sources.
