### Bug description

When using `docx` format and generating a table with multiple sub-tables, the overall caption of the tables appears at the bottom of the table instead of the top. For example, compare the two tables in this document:

````quarto
---
title: "Bad caption placement"
format: docx
---

# Single table with caption on top

```{r}
#| label: tbl-one
#| tbl-cap: "Caption on top"
library(knitr)
kable(head(cars))
```

# Sub-tables with overall caption on bottom

```{r}
#| label: tbl-two
#| tbl-cap-location: top
#| tbl-cap: "Caption on bottom"
#| tbl-subcap: 
#|   - "Cars"
#|   - "Pressure"
library(knitr)
kable(head(cars))
kable(head(pressure))
```
````

The second table has the overall caption at the bottom. This behavior is inconsistent with other output formats (both `html` and `pdf` place the overall caption at the top) and does not appear to be controllable with `tbl-cap-location`.
