When real shadow DOM is on, the event.target of this listener changes from the dropdown to the breadcrumbs component. This is because of shadow DOM event retargeting. To solve this, we use Polymer to normalize the event and get the real root target, px-dropdown, whether we are in shadow DOM or shady DOM.
