### Bug description

Tables with markdown or html have to have `escape = FALSE` to not show the markdown or html verbatim when displaying in a table with kable(). 

- If you you display the table with `knitr::kable()`, both types of links display correctly as links
- If you use `kableExtra::kable()`, the markdown version just shows the markdown verbatim
- However, if you `unclass()` the result of the kableExtra version, it does display markdown links correctly
- The reprex below shows these problems in a .qmd file, but not if knit in an .Rmd file

Reprex of the problem:

````
---
title: "kableExtra Escape Reprex"
format: html
---

Create table with markdown and html links:

```{r}
tbl <- data.frame(
  markdown = "[github](https://github.com)",
  html = "<a href='https://github.com'>github</a>"
)
```

Both work with knitr::kable()

```{r, results='asis'}
knitr::kable(tbl, escape = FALSE) 
```

The markdown version doesn't work with kableExtra::kable()

```{r, results='asis'}
kableExtra::kable(tbl, escape = FALSE) 
```

But if you unclass() and cat() the result, it does work:

```{r, results='asis'}
kableExtra::kable(tbl, escape = FALSE) |>
  unclass() |> cat()
```

### `quarto check` Output

FYI: for RStudio users who aren't familiar with the command line, you might want to instruct them to paste the output of `quarto::quarto_path() |> paste("check") |> system()`.
