--- Comment #10 from Damjan Jovanovic <damjan.jov at gmail.com> ---
Adding a stubbed ieframe:ClientSite_GetContainer() didn't help, even though all
the methods called (LockContainer, Release) return S_OK.

However I did see I was wrong. GenerateAppHtmlPage() and LoadBrowserDocument()
are not functions in some third-party library, they are within-application
functions in source/windows/GUITools.cpp.

GenerateAppHtmlPage() converts the HTML fragment into a full HTML page, by
adding surrounding <html> and <body> tags etc.

LoadBrowserDocument() is more interesting:
---snip---
void LoadBrowserDocument(TWebBrowserEx * WebBrowser, const UnicodeString &
Document)
{
  std::unique_ptr<TMemoryStream> DocumentStream(new TMemoryStream());
  UTF8String DocumentUTF8 = UTF8String(Document);
  DocumentStream->Write(DocumentUTF8.c_str(), DocumentUTF8.Length());
  DocumentStream->Seek(0, 0);

  // For stream-loaded document, when set only after loading from
OnDocumentComplete,
  // browser stops working
  SetBrowserDesignModeOff(WebBrowser);

  TStreamAdapter * DocumentStreamAdapter = new
TStreamAdapter(DocumentStream.get(), soReference);
  IPersistStreamInit * PersistStreamInit = NULL;
  if (DebugAlwaysTrue(WebBrowser->Document != NULL) &&
      SUCCEEDED(WebBrowser->Document->QueryInterface(IID_IPersistStreamInit,
(void **)&PersistStreamInit)) &&
      DebugAlwaysTrue(PersistStreamInit != NULL))
  {
    PersistStreamInit->Load(static_cast<_di_IStream>(*DocumentStreamAdapter));
  }
}
---snip---

We don't seem to get as far as PersistStreamInit->Load(), which is a stub on
our side anyway.
