How convert svg to png (in bash or nodejs) with background raster image?

Question

I insert background image to svg like described here Now I need convert it to png on server side. I try bash command:

 convert -density 1200 march.svg march.png

In result I see svg only without background raster image. Also I try npm svg-to-png and also not see background.

How I can resolve this issue? Thanks!

UPD:

Downliad march.svg
