How to label mermaid diagrams saved as images?

[IndrajeetPatil]

Description

When I save the mermaid diagrams as PNG/SVG in gfm or html format, I wish them to be named more informatively than mermaid-figure-1, etc.

I tried label, but it does not seem to work. Any ideas?

E.g. the following gfm-1.qmd would produce gfm-1_files/figure-commonmark/mermaid-figure-1.png, instead of fig-rest-api-architecture.png:

---
format:
  gfm:
    mermaid-format: png
---

```{mermaid}
%%|  label: fig-rest-api-architecture
graph TD
    A[Hard edge] -->|Link text| B(Round edge)
    B --> C{Decision}
    C -->|One| D[Result one]
    C -->|Two| E[Result two]
```

I don't believe you can as it's hardcoded:

• quarto-cli/src/core/handlers/mermaid.ts

  Line 342 in 6eb757f

  prefix: "mermaid-figure-",

• quarto-cli/src/core/handlers/mermaid.ts

  Line 312 in 6eb757f

  "mermaid-figure-",

This would be a feature request to allow to mermaid figure to use label as filename.
