Please provide us with the SVG file itself.

Ah, sorry, just saw that the SVG is downloadable ...

This is not a PyMuPDF problem. All functions required for your task are done by our base library directly.
I am therefore going to forward the issue to MuPDF's system.
Currently receiving gateway timeouts so please bear with us. In the meantime, you can confirm confirm yourself by doing e.g. this

mutool convert -o mutool-test.png test.svg

Thank you!
Just FYI, I ended up using another library because of this. Please feel free to close the issue if you'd like
