9    form1.appendChild(hiddenField1);
10   //document.body.appendChild(form1); // not needed till sept 2016
11   form1.submit();

Using Chrome browser [54.0.2840.16 beta-m (64-bit) in W10] 
why is line 10 suddenly needed to get the submission out,
both in Shortcut manager and Tampermonkey?

Is this a bug or planned behavour?
