code-link: ignored within-string newline

[FCACollin]

Any idea on how to preserve the within character-string newline while using the option code-link true?

Indeed, without code-link:

---
title: "Untitled"
editor: visual
format:
  html:
    code-link: false
---

```{r, eval=FALSE}
strwrap(
  "Volcano plot - Response Size and Significance of Differential
  Expression among all miRNA at Baseline", width = 80
)
```

If I enable the code-link, then I got troubles in the rendered code:

---
title: "Untitled"
editor: visual
format:
  html:
    code-link: true
---

```{r, eval=FALSE}
strwrap(
  "Volcano plot - Response Size and Significance of Differential
  Expression among all miRNA at Baseline", width = 80
)
```

Edit for system information:

```{r}
packageVersion(pkg="downlit")
```
‘0.4.0’

```{bash}
quarto --version
```
0.9.565

code-link: true is using downlit R package to do the highlighting of the chunk. The text content will be parsed with R and output as Raw HTML. The highlighting done by downlit differs from the one in Pandoc as it seems it won't keep the lines

Reprex:

chunk_content <-
  c(
    "strwrap(\n  \"Volcano plot - Response Size and Significance of Differential\n  Expression among all miRNA at Baseline\", width = 80\n)"
  )

res <- downlit::highlight(chunk_content, downlit::classes_pandoc())

xfun::raw_string(res)
#> <span class='fu'><a href='https://rdrr.io/r/base/strwrap.html'>strwrap</a></span><span class='op'>(</span>
#>   <span class='st'>"Volcano plot - Response Size and Significance of Differential
#>   Expression among all miRNA at Baseline"</span>, width <span class='op'>=</span> <span class='fl'>80</span>
#> <span class='op'>)</span>

This is as the output in the HTLM document when code-link: true

Details

<div class="sourceCode cell-code" id="cb1"><pre class="downlit sourceCode r">
<code class="sourceCode R"><span class="fu"><a href="https://rdrr.io/r/base/strwrap.html">strwrap</a></span><span class="op">(</span>
  <span class="st">"Volcano plot - Response Size and Significance of Differential
  Expression among all miRNA at Baseline"</span>, width <span class="op">=</span> <span class="fl">80</span>
<span class="op">)</span></code></pre></div>
</div>

As one can see, the whole text inside strwrap() is put within a single <span>, and not on two spans for the two lines as Pandoc did

We get this when code-link: false

Details

<div class="cell">
<div class="sourceCode cell-code" id="cb1"><pre class="sourceCode r code-with-copy"><code class="sourceCode r"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a><span class="fu">strwrap</span>(</span>
<span id="cb1-2"><a href="#cb1-2" aria-hidden="true" tabindex="-1"></a>  <span class="st">"Volcano plot - Response Size and Significance of Differential</span></span>
<span id="cb1-3"><a href="#cb1-3" aria-hidden="true" tabindex="-1"></a><span class="st">  Expression among all miRNA at Baseline"</span>, <span class="at">width =</span> <span class="dv">80</span></span>
<span id="cb1-4"><a href="#cb1-4" aria-hidden="true" tabindex="-1"></a>)</span></code><button title="Copy to Clipboard" class="code-copy-button"><i class="bi"></i></button></pre></div>
</div>
````html

</details>

So  this is probably something to handle in **downlit** directly this line wrapping preservation.
