svg with embedded base64 encode svg renders transparent image

[eNepper]

I tried processing the following svg, but it resulted in a transparent image with the width and height of the svg.

Hello, the pre-compiled librsvg shared library provided by sharp is compiled using the --disable-pixbuf-loader flag to slightly simplify a somewhat-complex thing. As you've discovered this prevents nested SVGs from rendering.

I've created lovell/sharp-libvips#9 to track the work to attempt to deal with this.

To workaround this for now you'll need to globally install custom installations of librsvg and libvips.

This won't be possible with prebuilt binaries, sorry, you'll need to globally install of librsvg and libvips. lovell/sharp-libvips#9 (comment)
