87      NOTE: Adding observer to an element is just like addEventLi
 >stener, if you observe the element multiple times it does not mak
 >e a difference. Meaning if you observe element twice, the observe
 > callback does not fire twice, nor will you have to run disconnec
 >t() twice. In other words, once an element is observed, observing
 > it again with the same will do nothing. However if the callback 
 >object is different it will of course add another observer to it.
