[quarto] tables with fmt_markdown don't render in quarto dashboard

• If there is already a relevant issue, whether open or closed, comment on the existing thread instead of posting a new issue.

Description

I have a quarto dashboard, converted from an html file, in which some but not all gt tables fail to render. I was able to isolate the behavior only to those tables using fmt_markdown. In all my exmaples, the markdown string includes a <br/>. I'm not sure if this extends to other contents.

Reproducible example

• Post a minimal reproducible example so the maintainer can troubleshoot the problems you identify. A reproducible example is:
  • Runnable: post enough R code and data so any onlooker can create the error on their own computer.
  • Minimal: reduce runtime wherever possible and remove complicated details that are irrelevant to the issue at hand.
  • Readable: format your code according to the tidyverse style guide.

## row

```{r}
#| title: with markdown
library(gt)
library(dplyr)
library(glue)
h <- head(sp500, n = 3) |> 
  mutate(test = glue::glue('{LETTERS[row_number()]}<br/>test')) |>
  gt() |>
  fmt_markdown(columns = c(test))
h
```

# session

```{r}
sessioninfo::session_info()
```

Expected result

I expected the table to render within the card. Instead, the rendered document is blank.

I'm using quarto version: 1.4.551

I would like to note that using md() for changing cols_label() yields the same behavior, and that it works as expected with gt 0.10.0.

## Heading

```{r}

 gt::gt() |>
  cols_label(
    num = md("**here**")
  )
```

I can confirm this is a Quarto issue.

Though @rich-iannone using <span data-qmd instead of <div data-qmd avoid the issue.

Maybe not using div always could be a good idea. Also content is duplicated like this

<div data-qmd="**here**"><div class='gt_from_md'><p><strong>here</strong></p>
</div></div>

and this will create two entry in the table. But maybe this is a Quarto issue, as the content of the div should probably be ignored when processed 🤔

i'll look into it
