This is to add a rootScope broadcast from the backdrop service. This is really useful in hybrid apps involving native views. E.g. native maps or camera.
Generally any time the backdrop is shown the developers wants this to be on top of everything and nothing below it to be clickable or receive input, this generally means sending a cordova message to native components telling them something is on top. This broadcast allows that to be easily implemented once for whenever the backdrop appears. Ionic already has something similar for modals.
