Links for cross-references with explicit an ID don't work with HTML output

[somelinguist]

With the following markdown from readme.md, the div's ID in the HTML output gets overwritten to ex4.13 instead of test.

::: {#test .ex}
This is a test
:::

pandoc-ling/docs/readme.html

Lines 722 to 731 in a9eae71

	<div id="ex4.13">
	<table class="linguistic-example">
	<tbody>
	<tr class="odd">
	<td class="linguistic-example-number" style="vertical-align: top;">(4.13)</td>
	<td class="linguistic-example-content" style="text-align: left;">This is a test</td>
	</tr>
	</tbody>
	</table>
	</div>

However, the cross-references using [@last], etc. maintain test as the ID to link to (the following is taken from readme.html, line 732):

<code>[@last]</code> will be formatted as <a href="#test">(4.13)</a>

Likewise, in line 733:

<code>[@last hA1l0]</code> will work also, leading to <a href="#test">(4.13 hA1l0)</a>

and line 717:

<code>[@test]</code>, leading to <a href="#test">(4.13)</a>

The ID for the div gets reset for HTML output in line 276 of pandoc-ling.lua

pandoc-ling/pandoc-ling.lua

Lines 268 to 277 in a9eae71

	-- reformat!
	local example
	if FORMAT:match "latex" or FORMAT:match "beamer" then
	example = texMakeExample(parsedDiv)
	else
	example = parsedDiv.examples
	example = pandocMakeExample(parsedDiv)
	example = pandoc.Div(example)
	example.attr = {id = "ex"..parsedDiv.number}
	end

Following the proposal one should be able to link from an external source to something like webpage.url/#ex4.13, should the code that makes the cross-references for HTML also change the ID to #ex4.13 instead of #test?

pandoc-ling/pandoc-ling.lua

Lines 1538 to 1547 in a9eae71

	-- make the cross-reference
	if FORMAT:match "latex" then
	if latexPackage == "expex" then
	return pandoc.RawInline("latex", "(\\getref{"..id.."}"..suffix..")")
	else
	return pandoc.RawInline("latex", "(\\ref{"..id.."}"..suffix..")")
	end
	else
	return pandoc.Link("("..indexEx[id]..suffix..")", "#"..id)
	end

Actually, for the HTML output, if you wanted, you could make a link using either #test or #ex4.13 work if line 276 set the div's ID to test, and then added an ID for something like the cell containing the example number itself to ex4.13:

pandoc-ling/pandoc-ling.lua

Lines 556 to 558 in a9eae71

	-- Add example number to top left of first table
	local numberParen = pandoc.Plain( "("..parsedDiv.number..")" )
	example[1].bodies[1].body[1].cells[1].contents[1] = numberParen
