How can I have a theme-sensative SVG?

[benjitusk]

I have 2 SVG files on disk, and I want to display the appropriate one depending on the theme. I read the docs where it says to append #only-light and #only-dark to the file path, but it seems to be breaking (when I use mkdocs serve), presumably because it thinks #only-dark is part of the actual file path. Has anyone else managed with this?

A minimal reproduction goes a long way ☺️ It's much easier to help you if we have a self contained example that we can run.
