Just make a invisible layer over the iframe that go back when click and go up when mouseleave event will be fired !!
Need jQuery

this solution don't propagate first click inside iframe!

$("#invisible_layer").on("click",function(){
		alert("click");
		$("#invisible_layer").css("z-index",-11);

});
$("iframe").on("mouseleave",function(){
		$("#invisible_layer").css("z-index",11);
});

iframe {
    width: 500px;
    height: 300px;
}
#invisible_layer{
  position: absolute;
  background-color:trasparent;
  width: 500px;
  height:300px;
}
