Both figure and table captions are being converted to actual table structures within Word. This results in the captions being displayed as tables, not text, completely breaking the document layout and structure.

Bug description

"I'm encountering a significant issue when converting Quarto documents to Word (.docx) format. Instead of correctly rendering figure and table captions as either "Image Caption" or "Table Caption" styles, Quarto is erroneously converting them into actual Word "Table" elements. This means that the captions are not displayed as text paragraphs but are instead rendered as full-fledged tables within the Word document. This is a very peculiar and serious error, as the captions should clearly be text content associated with figures and tables, not actual tables themselves.
To be more specific:
Expected behavior: Figure captions should be rendered using the "Image Caption" style in Word, and table captions should be rendered using the "Table Caption" style (or at least as normal paragraph text associated with table/figures ).
Actual behavior: Both figure and table captions are being converted to actual table structures within Word. This results in the captions being displayed as tables, not text, completely breaking the document layout and structure.
This is happening in all cases, regardless of whether the caption is for a figure or a table. I've checked for any potential configuration issues and verified that my Pandoc setup is correct, which leads me to believe that this might be a bug within Quarto itself.
I would be grateful if you could investigate this issue and provide a potential workaround or solution."

Steps to reproduce

---
title: "test"
execute:
    keep-md: true
format: 
  docx: 
    df-print: kable

---

## Quarto
```{r}
#| echo: false
#| warning: false
#| tbl-cap: iris
#| table-style: CaptionStyle
#| label: notbl-iris


head(iris) |>
  pander::pander()
  
```
  


```{r}
#| echo: false
#| warning: false
#| tbl-cap: hello
#| table-style: CaptionStyle
#| label: tbl-tcmdatapath


head(iris) |>
  pander::pander()
```

Expected behavior

Figure captions should be rendered using the "Image Caption" style in Word, and table captions should be rendered using the "Table Caption" style (or at least as normal paragraph text associated with table/figures

Actual behavior

Both figure and table captions are being converted to actual table structures within Word. This results in the captions being displayed as tables, not text, completely breaking the document layout and structure.
