Doesn't work with ipyleaflet

For example when running the following code

from ipyleaflet import Map, basemaps, basemap_to_tiles
import jupyter_capture_output

%%capture_img --path "canada.png"
m = Map(
    basemap=basemap_to_tiles(basemaps.CartoDB.Positron),
    center=(51, -120),
    zoom=6,
    )
m

It says Output saved by creating file at canada.png., but no image appears in the working directory.
