           Summary: HtmlDocument.Equals and op_Equality infinite recursion

HtmlDocument.Equals calls op_Equality which calls Equals.  If passed two
separate instances then infinite mutual recursion occurs and stack overflow
results.

    WebBrowser wb = … // Reference some valid instance with page loaded...
    HtmlDocument d = wb.Document;
    // A hack to get another HtmlDocument instance
    HtmlDocument d2 = d.Body.Document;
    bool eq = d.Equals(d2); // stack overflow

With the repro app from bug 428172, hit Test->HtmlDocument.Equals.  See stack
overflow crash.
