Description

Quarto support Pandoc's header_attributes. But if .unnumbered or .unlisted is used, then the identifier doesn't get applied as a Typst label.

## Funding {#frontmatter .unnumbered .unlisted}
{{< lipsum 1 >}}

// no  label

# Introduction {#intro}
{{< lipsum 3 >}}

// label: <intro>

## H2: Main Section
{{< lipsum 3 >}}

// label: <h2-main-section>

#block[
#heading(
level: 
2
, 
numbering: 
none
, 
outlined: 
false
, 
[
Funding
]
)
]
...
= Introduction
<intro>
...
== H2: Main Section
<h2-main-section>

Thanks for the reporting - I think this may be a difference with pandoc as we handle it directly in Quarto

quarto-cli/src/resources/filters/quarto-post/typst.lua

Lines 55 to 73 in c9008d7

	Header = function(el)
	if number_depth and el.level > number_depth then
	el.classes:insert("unnumbered")
	end
	if not el.classes:includes("unnumbered") and not el.classes:includes("unlisted") then
	return nil
	end
	local params = pandoc.List({
	{"level", el.level},
	})
	if el.classes:includes("unnumbered") then
	params:insert({"numbering", pandoc.RawInline("typst", "none")})
	end
	if el.classes:includes("unlisted") then
	params:insert({"outlined", false})
	end
	params:insert({_quarto.format.typst.as_typst_content(el.content)})
	return _quarto.format.typst.function_call("heading", params)
	end,

Pandoc does now handle it and set lab always

Unumbered is supported since pandoc 3.1.13 (may 2024) - so more recently

• [Typst writer] Section headers does not respect .unnumbered jgm/pandoc#9585

We should probably adapt.
