Google Maps JavaScript API - fitbounds together with setCenter

Question

I've been looking around for a solution to this problem, but i can't seem to find somthing that solves this. The closest i get is this thread. But this doesn't work.

What i'm trying to do is to run fitbounds based on a set of markers which works fine. But i would also like to center the map based on the users location (the bouncing marker in the plunk) and still keep all markers within the map view. If i try to setCenter after fitBounds, some markers are outside of the map view. Is there some nifty way of combining these two functions? Here's the plunk illustrating the issue.

function initialize() {
  var userCenter = new google.maps.LatLng(51.508742, -0.120850);

  var userCenterMarker = new google.maps.Marker({
  position: userCenter
});

 userCenterMarker.setAnimation(google.maps.Animation.BOUNCE);

var mapProp = {
  center: userCenter,
  zoom: 12,
  mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("googleMap"),   mapProp);

var bounds = new google.maps.LatLngBounds();
var markers = getMarkers();

$(markers).each(function() {
  bounds.extend(this.position);
  this.setMap(map);
});

userCenterMarker.setMap(map);

map.fitBounds(bounds);

setTimeout(function() {
  map.setCenter(userCenter);
}, 1500);
}

Thanks!

Simple solution: Add your "user marker" to the bounds, do fitBounds, then decrement the resulting zoom by 1 and center on that marker.

  bounds.extend(userCenterMarker.getPosition());
  map.fitBounds(bounds);

  google.maps.event.addListenerOnce(map,'bounds_changed', function() {
        map.setZoom(map.getZoom()-1);
  });

More complex solution: Center on the "user marker", check to see if the marker bounds is completely included in the map's current bounds (map.getBounds().contains(markerBounds)), if not, decrement the zoom level by 1.

The above answer didn't work for me. Here's what did:

contained = true;
map.fitBounds(bounds);
map.setCenter(center);
newbounds = map.getBounds();
for (i = 0; i < l; i ++) {
  if (!newbounds.contains(markers[i].getPosition())) {
    contained = false;
  }
}
if (!contained) map.setZoom(map.getZoom() - 1);
