Mapbox.js - image with a reduced style from a lower zoom level if the required zoom level is missing

I serve png png files from disk, and I have png fragments for the entire city at zoom level 15. I also have tiles in zoom levels 16-18, but only for certain areas.

I would like to adjust the tile layer so that when the user reaches zoom level 18, the map will display scaled fragments from level 15 as a backup.

I tried to set the parameter maxNativeZoombut did not work for me.

Here is my code:

offlineLayer = L.mapbox.tileLayer(tileJSON, {
    minZoom: 8,
    maxZoom: 18,
    maxNativeZoom: 15
});
map.addLayer(offlineLayer, 'Offline', 1);

Can I make it work using some parameters or do I need to hack it somehow? Or is there some kind of code sample for this?
