quarto messes up svg links

Bug description

I generated a svg with a link using plantuml:

@startuml
start
if (condition A) then (yes)
  :[[#subroutine1 Text 1]];
elseif (condition B) then (yes)
  :Text 2;
  stop
(no) elseif (condition C) then (yes)
  :Text 3;
(no) elseif (condition D) then (yes)
  :[[#subroutine-2 Text 4]];
else (nothing)
  :Text else;
endif
stop
@enduml

which generated the follwing svg diagram with 2 links to #subroutine1 and #subroutine-2.

I created a quarto document as

---
format:
  html:
    toc: true

title: Links in plantuml
author: Me
---


# Main Function

![ ](./main.svg)


# Subroutine1



# Subroutine 2

When I create the html with

quarto render svglinks.qmd -M embed-resources:true 

the links are changed to #svg_615cf2f8e2489f045e4e_subroutine-2 and #svg_615cf2f8e2489f045e4e_subroutine1 which, of course, breaks the links to the headers.

On the other hand, if I use rmarkdown:

rmarkdown::render("svglinks.qmd")

the generated HTML has the correct links.

Steps to reproduce

No response

Expected behavior

links in svg should be preserved as is

Actual behavior

links are being changed by adding a random suffix

Your environment

MacOS Sonoma 14.1.1 (23B81)

Start with the provided svglinks.qmd and main.svg, then run quarto render svglinks.qmd -M embed-resources:true and inspect the generated HTML anchors. Compare the embedded SVG links with the document headers and the output from rmarkdown; done means the PlantUML links still resolve to the intended headers after Quarto rendering.
