Confluence does not show `gt()` tables correctly

Bug description

I am not sure, if this is Quarto issue, or gt() library's issue or Confluence, so I apologize if I address the issue using the wrong channel.

I have written a report using .qmd and published it on confluence. In my report i did use gt() and gtsummary() libraries to create tables. In quarto preview the tables are rendered and displayed correctly, however once published, the tables are are displayed as broken.

Steps to reproduce

---
title: "test"
format: html-confluence
---

## This is a test

```{r}
suppressMessages(library(tidyverse))
library(gt)
```

```{r}
mtcars|>
    group_by(cyl)|>
    summarise(avg_mpg=mean(mpg))|>
    gt()|>
    tab_header(title = "The title of the table")
```
