In order to figure out where the problem happens, the execution of the proposed test case is run step by step under gdb, comparing what happens with :

document.dispatchEvent(evt);

where document is the document being displayed and

doc.dispatchEvent(evt);

where doc is the result of

var doc = parser.parseFromString(thatDoc, 'text/xml');

It differs in

  void JSEventListener::handleEvent(ScriptExecutionContext* scriptExecutionContext, Event* event)
  {
...
    JSDOMGlobalObject* globalObject = toJSDOMGlobalObject(scriptExecutionContext, m_isolatedWorld.get());
      if (!globalObject)
          return;
...
}

where globalObject is null for the parsed XML document and the handler is therefore not fired. The reason why it is null is because the scriptExecutionContext->frame() function returns null. It matches the diagnostic of the bug report claiming that the problem does not exist when the XML document is loaded using an iframe.
