L.TileLayer.MVTSource could request tiles with invalide x an y

[haoliangyu]

I have a local vector tile server based on tilesplash and use L.TileLayer.MVTSource to load the vector tile layer at the client side:

var map = L.map('map').setView([0, 0], 2);

var layer = new L.TileLayer.MVTSource({
    url: 'http://localhost:3000/my_layer/{z}/{x}/{y}.mvt'
})

map.addLayer(layer);

I notice that the L.TileLayer.MVTSource could send request with invalid x and y parameter:

• x or y smaller than 0

http://localhost:3000/my_layer/2/-1/1.mvt

• x or y larger than the available number based on the zoom level

http://localhost:3000/my_layer/2/4/2.mvt

Is it a bug, or just because of incorrect layer config?

I am experiencing the same problem.
