svg links work in HTML but not in PDF

Start by rendering the provided .qmd file to PDF with use-rsvg-convert enabled, comparing the remote DOI SVG with the local SVG. Trace the PDF/SVG conversion entry point; done when the remote linked SVG renders successfully without the missing 569245031_svg-tex.pdf error.

Bug description

A badge in SVG format works in our book when rendering as HTML, but not when rendering as PDF.
Since version 1.3 quarto automatically transform SVG images for PDF output.
This however, appears to work only with local files and no links.

Steps to reproduce

With the following *.qmd file:

---
title: "title"
subtitle: "subtitle"
author: "me, & them"
nocite: |
  @*
format:
  pdf:
    toc: true
    toc-depth: 2
    number-sections: true
    number-depth: 2
    use-rsvg-convert: true
    output-file: "test"
    output-ext:  "pdf"
    # resource-path: ["book/figures/"]
    # linkcolor: RSSblue
    # urlcolor: RSSblue
    # include-in-header: 
    #    - "_styles.tex"
editor: source
---

![DOI](book/figures/zenodo.7740560.svg)        <!-- This works -->
