manuscript project not rendering when there is a labelled code chunck

Bug description

A qmd document is well rendered with figures and tables labelled. But when the document is used as manuscript project, quarto fails to render the manuscript project if there one labelled code chunck. Jupyter kernel starts and carries out the computation in the code chunck but quarto fails to render if there is at least one labelled code chunk: I have tested *| label: fig-tagand *|tbl-tag.

Steps to reproduce

title: Quarto Manuscript Default Project

  - name: Norah Jones

    roles: writing
    corresponding: true
bibliography: references.bib
jupyter: nbstata

## Section
This is a simple placeholder for the manuscript's main document [@knuth84].

The document fails to render once the below code chunk @fig-figuretag1 is labelled with `*| label: fig-figurelabel`.


```{stata}
*| label: fig-figuretag1
*| fig-cap: From code chunck
*| echo: false

qui webuse auto, clear
scatter price mpg
```

The same happens if there is one table code chunk labelle with `*| label: tbl-tablelabel`.

@fig-figuretag1 worked well from code chunk. 

and @tbl-tabletag1 embedded after being produced in a the code chunk below.

```{stata}
*| include: false
table foreign, stat(mean price) stat(sd price)
collect layout (foreign) (result)
collect style cell result, font("Trade Gothic Next", bold size(12))
collect export tab1, as(html) replace
```

Even here we refer to the same html table @tbl-tabletag1 

::: {#tbl-tabletag1}

```{stata}
*| echo: false
*| output: asis
display "```{=html}"
type tab1.html
display "```"
```

Produced dynamically from formatted html table

:::

```{stata}
*| echo: false
*| include: false
table foreign, stat(mean price) stat(sd price)
collect layout (foreign) (result)
*collect style cell result, font("Trade Gothic Next", bold size(12))*
collect export tab2, as(md) replace
```

And when @tbl-tabletag2 is produced from Markdown table

::: {#tbl-tabletag2}

```{stata}
*| echo: false
*| output: asis
type tab2.md
```

Produced dynamically from md table

The End

Expected behavior

The qmd document should render and add cross-reference in a single document as well as in manuscript project.

Actual behavior

In a manuscript project the same document fails to render if there is at least one labelled code chunk, be it labelle with code chuck label: tbl-, label: fig- or fenced div.

When there is a *| label: fig- in the index.qmd, there produced error is:

Reproduce the failure with the manuscript project's index.qmd, comparing labelled figure/table code chunks and fenced divs. Start from the reported rendering path and main.lua errors, then verify that the manuscript renders successfully with cross-references preserved, as the standalone qmd already does.
