   I think this is an issue as we use jog traversal which will mutate element, and we do unroll div
   

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

   Lines 72 to 91 in 537a0f9

   	function jats()
   	if _quarto.format.isJatsOutput() then
   	return {
   	Meta = jatsMeta,
   	-- clear out divs
   	Div = function(div)
   	if isTableDiv(div) then
   	local tbl = div.content[1]
   	if tbl.t == "Table" then
   	tbl.identifier = div.identifier
   	end
   	return tbl
   	else
   	-- otherwise, if this is a div, we can unroll its contents
   	-- TODO can we replace this by a single return div.content?
   	return unrollDiv(div, is_custom_node)
   	end
   	end,

   So I think this is modifying the node.node element of the ConditionalBlock custom node:
   

   quarto-cli/src/resources/filters/customnodes/content-hidden.lua

   Lines 58 to 67 in 537a0f9

   	render = function(node)
   	local visible = is_visible(node)
   	if visible then
   	local el = node.node
   	clearHiddenVisibleAttributes(el)
   	return el.content
   	else
   	return {}
   	end
   	end,

   and this make the custom ast render fail.

   So I need to find the right way. This is a bit different than pandoc.List() , pandoc.Blocks({}) change.
