   Is it possible to move the focus from the current radio button to the 
next component which does not belong to the current radio buttons group 
by pressing tab key?
   For example in the test FocusCycleRootTest from the issue 
description, moving the focus from the first and the second radio button 
to the text field 1 and from the third and the fourth radio button to 
the text field 2.

   Thanks,
