FsReveal Line Highlighting - f#

Question

I am trying to highlight lines in an FsReveal presentation. I want to show all the lines then in the next step highlight line 3. I know this is possible in Reveal.js but I am not sure how to use it from FsReveal. Here is what I tried:
***
- data-line-number : 1-3|3
### Chicken
```
let x = 10
let y = ["a"; "b"; "c"]
let monkey = 100.0
```
***
Instead of showing all the lines and then highlighting the third line on the next right-arrow, it just shows all the lines as normal and moves on.

I don't really have a working answer, but I have two thoughts that could help.
First, the data-line-numbers attribute needs to be set on the <code> element of your snippet. The way you are setting it, it will be copied to the <section> element. This is unfortunate, because the <code> element is generated from Markdown formatting, so you cannot directly set this. You can still have HTML elements in your markdown document, so you could try if this works:
<pre><code class="nohighlight" data-line-numbers="3,8-10">
<table>
<tr>
<td>Apples</td>
<td>$1</td>
<td>7</td>
</tr>
<tr>
<td>Oranges</td>
<td>$2</td>
<td>18</td>
</tr>
</table>
</code></pre>
This did not actually work for me, sadly, despite generating what looks like correct HTML. I suspect this is because FsReval uses an older version of reveal.js. There should be a way to update that.
If you got this to work, you could try setting the attribute on the generated <code> using JavaScript, right after your HTML element:
```
let x = 10
let y = ["a"; "b"; "c"]
let monkey = 100.0
```
<script>
var els = document.getElementsByTagName("code");
els[els.length-1].setAttribute("data-line-numbers","3,8-10");
</script>
