Is it possible in mapbox to pan the map to the marker onClick regarding the popup height?
Currently, the popup disappears behind the map's mask. I'm looking for a solution, to fit both into the map, the marker and the popup (like adding some top padding).
featureLayer.on('click', function(e) {
var latLng = e.layer.getLatLng();
map.panTo(latLng);
});

I have found a native solution.
You need add the parameter keepInView to the bindPopup() command.
layer.bindPopup('<p>Hello</p>', {keepInView: true});

Way late on answering this question, but I came across it so others might too. I was having a similar issue and Dan Mandle answered with this bit of code on a similar question:
map.on('popupopen', function(e) {
var px = map.project(e.popup._latlng); // find the pixel location on the map where the popup anchor is
px.y -= e.popup._container.clientHeight/2 // find the height of the popup container, divide by 2, subtract from the Y axis of marker location
map.panTo(map.unproject(px),{animate: true}); // pan to new center
});
This code worked great for me, and still allows for panning the map once the popup is open, unlike using keepInView.
