Custom crossref cannot be resolved

Bug description

I wanted to cross reference supplementary figures in my manuscript so I included a custom crossref for suppfig.
Unfortunately, after rendering quarto gives a warning:

WARNING (/opt/quarto/share/filters/main.lua:12315) Unable to resolve crossref @suppfig-demo-plot

I tested multiple possibilities to check if I am doing something wrong, but I think that is a bug.

Steps to reproduce

Render the following qmd:

---
title: "Title Goes Here"
author:
  - Jane Doe:
crossref:
  custom:
    - kind: float
      key: suppfig
      latex-env: suppfig
      reference-prefix: Figure S
      space-before-numbering: false
      latex-list-of-description: Supplementary Figure
---

# Results

```{r}
#| label: fig-demo-plot
#| fig-cap: "A plot of random numbers"
plot(rnorm(10))
```

```{r}
#| label: suppfig-demo-plot
#| fig-cap: "A plot of random numbers"
plot(rnorm(20))
```

@fig-demo-plot shows how we can have a caption and cross-reference for a plot. 

@suppfig-demo-plot shows how we can't have a caption and cross-reference for supplementary figures.

Expected behavior

I expect to get a rendered crossreference for a supplementary figure

Actual behavior

Now I get a warning that the reference could not be resolved, and the figure is not labeled.
