Printing tables in a loop fails with TeX/PDF output (quarto)

[cswingle]

Description

When printing a tables in a loop I get the proper output when choosing html format (via quarto), but the tables are not printing correctly in pdf format.

Reproducible example

Here's an example quarto document (loop_test.qmd):

Here are tables of mtcars by cylinder.

```{r}
#| echo: false
#| output: asis

library(tidyverse)
library(gt)

plot_by_cyl <- function (cyl_) {
  data <- mtcars %>% filter(cyl == cyl_)
  print(gt(data))
  # print(knitr::kable(data)). # <-- this works
}

walk(
  mtcars %>% pull(cyl) %>% unique() %>% sort(),
  plot_by_cyl
)
```

Expected result

When the document is rendered with quarto render loop_test.qmd --to html the individual tables show up as expected. When rendering with quarto render loop_test.qmd --to pdf, the tables do not show up. Instead each cell is printed on its own line.

When I comment out print(gt(data)) and uncomment print(knitr::kable(data)) in the code, I get the same tables in both HTML and PDF formats.
