```{r}
#| label: fig-test
#| layout-ncol: 3
#| fig-cap: main caption
#| fig-subcap:
#| - This

#| - test
x <- c(1:100)
y <- x+x+2
plot(x, y)
hist(y, breaks=5)
barplot(table(x,y))
I believe without `fig-cap`, and only `fig-subcap`, this will be considered as three figures, and `fig-subcap` will be passed as `fig-cap`, just using letters instead of numbers (because `\subcaption{}` is used instead if `\caption{}`).
I think this falls under both of this next work

We need to document the canonical markdown produced for this case, and check **knitr** is doing the right thing.
Out of curiosity I looked in past version for this content
````markdown
```{r}
#| layout-ncol: 3
#| fig-subcap:
#| - This
#| - is a
#| - test
x <- c(1:100)
y <- x+x+2
plot(x, y)
hist(y, breaks=5)
barplot(table(x,y))
* Quarto 1.4.555
* Quarto v1.3.450
* Quarto v1.2.475
So we have various behaviors over time.
Though our doc for subcaptions (https://quarto.org/docs/authoring/figures.html#subcaptions) uses `optionnaly` for the `fig-` label
> You can create subcaptions for computational output by combining the fig-cap and fig-subcap options. When applying captions to computational output you can **optionally** include a label with a fig- prefix—if you do this then the figure will be numbered and [cross-referenceable](https://quarto.org/docs/authoring/cross-references.html).
But `label: fig-` seems to be needed for this to work
Doing
````markdown
```{r}
#| layout-ncol: 3
#| fig-cap: Main Caption
#| fig-subcap:
#| - This
#| - is a
#| - test
x <- c(1:100)
y <- x+x+2
plot(x, y)
hist(y, breaks=5)
barplot(table(x,y))
yields
which is not what is document 🤔
Bug description
When plotting multiple figures in a single chunk with parameters such as
layout-ncol: 3andfig-subcap, the subcaption numbering is incorrect in the PDF output. All subcaptions start with "a)" instead of incrementing as expected ("a)", "b)", "c)", etc.).Steps to reproduce
Create and render this document to PDF.
Or use minimal example here https://github.com/produnis/minimal_examples/tree/subcaption
Expected behavior
The 3 figures are numbered "a)", "b)", "c)"
Actual behavior
The 3 figures are numbered as "a)" "a)" "a)".
