tbl-pos is ignored when set with layout-ncol on a crossref divs

Hi,
I think i found a bug when trying to created multiple tables and render them into latex.

Here the example

---
title: "Untitled"
format: 
    pdf:
        header-includes: | 
            \usepackage{lipsum}
---

## Case 1

\lipsum[1-2]

:::{#tbl-tm1 tbl-pos="H"}
| A | B | C |
|---|---|---|
| 1 | 2 | 3 |

Nice Table: Right where it belongs
:::
\lipsum[1-2]

## Case 2

\lipsum[1-2]

:::{#tbl-tm2 tbl-pos="H" layout-ncol="2"}

:::{#tbl-tm2a}
| A | B | C |
|---|---|---|
| 1 | 2 | 3 |

Table1: 
:::

:::{#tbl-tm2b}
| A | B | C |
|---|---|---|
| 1 | 2 | 3 |

Table2: 
:::

Not so nice: Where Latex Wants it
:::

\lipsum[1-2]

Interestingly, this doesn't happen if i do not use layout-ncol="2".

For Reference, I'm using Quarto 1.4.554

and here the rendered Document
Untitled-3.pdf

Putting back example I shared

It seems to be related to tbl-pos handling.

title: "Untitled"
format: pdf
keep-tex: true

## Case 1

{{< lipsum 1 >}}

:::{#tbl-tm tbl-pos="H"}

:::{#tbl-tma}
| A | B | C |
|---|---|---|
| 1 | 2 | 3 |

Table1: 
:::

:::{#tbl-tmb}
| A | B | C |
|---|---|---|
| 1 | 2 | 3 |

Table2: 
:::

This table as `tbl-pos`
:::

{{< lipsum 1-2 >}}

:::{#tbl-tm2 tbl-pos="H"}

::: {layout-ncol=2}

:::{#tbl-tm2a}
| A | B | C |
|---|---|---|
| 1 | 2 | 3 |

Table1: 
:::

:::{#tbl-tm2b}
| A | B | C |
|---|---|---|
| 1 | 2 | 3 |

Table2: 
:::
:::

This table also as `tbl-pos` an a layout
:::

{{< lipsum 1-2 >}}

:::{#tbl-tm3 tbl-pos="H" layout-ncol=2}

:::{#tbl-tm3a}
| A | B | C |
|---|---|---|
| 1 | 2 | 3 |

Table1: 
:::

:::{#tbl-tm3b}
| A | B | C |
|---|---|---|
| 1 | 2 | 3 |

Table2: 
:::

This table as lost `tbl-pos`
:::

• First table have \begin{table}[H]
• Second table also have \begin{table}[H]
• But latest one does not : \begin{table}

It seems the latest syntax should be working... 🤔

but it seems we are only considering fig-pos on Panel and not tbl-pos

quarto-cli/src/resources/filters/layout/latex.lua

Lines 79 to 87 in 50b4cf1

	-- determine the environment (and pos) to use for a latex panel
	function latexPanelEnv(layout)
	-- defaults
	local env = latexFigureEnv(layout)
	local pos = attribute(layout.float or { attributes = layout.attributes or {} }, kFigPos)
	return env, pos
	end

So this works

## Case 1

{{< lipsum 1-2 >}}

:::{#tbl-tm3 fig-pos="H" layout-ncol=2}

:::{#tbl-tm3a}
| A | B | C |
|---|---|---|
| 1 | 2 | 3 |

Table1: 
:::

:::{#tbl-tm3b}
| A | B | C |
|---|---|---|
| 1 | 2 | 3 |

Table2: 
:::

This table as lost `tbl-pos`
:::

{{< lipsum 1-2 >}}
 

I think we should compute based on the prefix of the float ref
Like in here:

quarto-cli/src/resources/filters/layout/latex.lua

Lines 513 to 527 in 50b4cf1

	-- Computes the figure position for a figure environment
	-- margin figures use offset instead of position
	function latexFigurePosition(el, env)
	if env == kMarginFigureEnv then
	return attribute(el, kOffset, nil)
	else
	local prefix
	if el.t == "FloatRefTarget" then
	prefix = ref_type_from_float(el)
	else
	prefix = refType(el.identifier) or "fig"
	end
	return attribute(el, prefix .. "-pos", nil)
	end
	end
