RevealJS `reference-location: section` does not number correctly

title: test
format:
  revealjs:
    center: true
reference-location: section
---

## Slide 1

- bullet one
- bullet two^[first footnote]
- This is the third bullet

## Slide 2

more test text here^[second footnote]

This leads to wrong numbering

Either this is an issue, or we should just disallow reference-location: section as I am not sure it makes sense in revealjs context

For context, we do special processing for footnotes in format-reveal.ts when not set to document level. So probably there to handle it correctly.

It does number correctly, but from level one header as for html format. Basically, if set it should either be ignored or account for level two (not one).

Sorry, I don't understand. In HTML the numbering of footnote is sequential and by default at the end. the reference-location: section just moves under each section but keeps the sequential numbering in the doc.

# Header 1 

## Sub 1

- bullet one
- bullet two^[first footnote]
- This is the third bullet

## Sub 2

more test text here^[second footnote]

# Header 2 

## Sub 3

more test text here^[second footnote]

For reveals, we do special process of footnotes when reference-location is not document (in format-reveal.ts), and so I am thinking something is not right as the sequential footnote is not changed

Never mind, the numbering is completely messed up with the option regardless of headings.

[cderv]

yes, this is why I opened the issue in the first place.

[mcanouil]

It's messed up but only in the footer.

FYI reference-location: document

[cderv]

Yes, as I said above in https://github.com/quarto-dev/quarto-cli/issues/8545#issuecomment-1922188181 we do a special processing in format-reveal.ts when reference-location is different than document.

This process is about getting the footnotes and splitting them on each related slides.
