docs: Returns whether <code>oDomRefChild</code> is contained in or equal to <code>oDomRefContainer</code>.
  
  This is a browser-independent version of the <code>.contains</code> method of Internet Explorer.
  For compatibility reasons it returns <code>true</code> if <code>oDomRefContainer</code> and
  <code>oDomRefChild</code> are equal.
  
  This method intentionally does not operate on the jQuery object, as the original <code>jQuery.contains()</code>
  method also does not do so.
