custom-music-fonts/smufl bravura SVG conversion broken

[tehunk]

Hi,

I noticed that the given snippet custom-music-fonts works great for creating a PDF score with Bravura, but SVG is broken. Is there any way to fix it?

Environment:

• macOS Mojave (10.14.6)
• lilypond 2.18.2 (from MacPorts)

Issue:

SVG output is broken.

This SVG was rendered on Firefox. It's equivalently broken on Chrome.

Reproduction step:

1. Installed the Bravura SVG font in lilypond/2.18.2/fonts/svg
2. Lilypond input file written (attached as 'test.ly')
3. Executed lilypond command lilypond -I <snippet-path> -dbackend=svg -o test-bravura test.ly

I've attached the pdf output as well for reference.

Thanks in advance
