Subtables increment table counter in cross-referenceable tables in `format: pdf`

Bug description

A #tbl- element with two tables inside increments the table counter by 3, rather than 1.

Possibly a variation of the problem in #7267.

Steps to reproduce

---
title: "Tables with weird numbering"
format: pdf
keep-md: true
keep-tex: true
---

::::: {#tbl-dfs layout="[[1, 1]]"}

::: {}
| Col1 | Col2 |
|------|------|
|      |      |
:::

::: {}
| Col1 | Col2 |
|------|------|
|      |      |
:::

dfs test
:::::


::: {#tbl-two}
| Col1 | Col2 |
|------|------|
|      |      |

Caption
:::

Expected behavior

Tables captions should be Table 1 and Table 2

Actual behavior

Table captions are Table 1 and Table 4.

(Side note: the tables seem to be getting different positioning treatment as well, probably because one in a \table and one a \longtable, might be something else to fix.)
