In this discussion http://stackoverflow.com/questions/20420189/rikulo-bootjack-polymerdart 
You suggest to wire the element into the shadow dom. I do it for the tooltip but it doesn't work for Alert.

I suggest to add an initialization method for shadow dom. It works for Alert but this method can be used on others components too.
Open for discuss about this solution.
