Set clip polygon but not work？

[liulangGG]

I set the clip option just like '[ [lat, lon], [lat, lon], [lat, lon] ]', when i use this latlngs to L.polygon(latlngs, {color: 'red'}).addTo(map), it is work, but when i set L.leafletGeotiff(url, { clip: latlngs, renderer: render }) , the map has no geotiff display, but if i don't set clip, it will work.
