awesome! i'll run some tests with your changes.

[jgravois]

all local tests passing for me and the change introduces the appropriate desired behavior.

var fl = L.esri.featureLayer('http://sampleserver6.arcgisonline.com/arcgis/rest/services/Census/MapServer/3', {
  minZoom: 5,
  maxZoom: 7,
}).addTo(map);

i'd like @patrickarlt to take a look too when he has the time. until then, thanks for the PR @MandarinConLaBarba!
