Are these expected to produce the same results? When using the PipeTables extension, Render() simply wraps the table cells in p tags (without and table, tbody, etc.). ToHtml() produces the full HTML table, as expected.

HtmlRender.Render() never hits a breakpoint in the HtmlTableRender.Write() method, whereas ToHtml() does. Am I missing a step for setting up the renderer object?

        public static void ParseMarkdown(string markdown)
        {
            var pipeline = new MarkdownPipelineBuilder().UsePipeTables().Build();
            MarkdownDocument md = Markdown.Parse(markdown, pipeline);
            var testStringA = md.ToHtml(pipeline);
            
            var stWriter = new StringWriter();
            var renderer = new HtmlRenderer(stWriter);
            renderer.Render(md);
            var testStringB = stWriter.ToString();
            
            Console.WriteLine(testStringA);
            Console.WriteLine(testStringB);
        }

(For context, I am exploring writing a different renderer.)

ToHTML() output (testStringA)

<h1>Table</h1>
<table>
<thead>
<tr>
<th><strong>Property</strong></th>
<th><strong>Description</strong></th>
</tr>
</thead>
<tbody>
<tr>
<td><strong>Interaction Manager</strong></td>
<td>The <a href="xr-interaction-manager.md">XRInteractionManager</a> that this Interactable will communicate with (will find one if <strong>None</strong>).</td>
</tr>
<tr>
<td><strong>Interaction Layer Mask</strong></td>
<td>Allows interaction with Interactors whose <a href="interaction-layers.md">Interaction Layer Mask</a> overlaps with any Layer in this Interaction Layer Mask.</td>
</tr>
<tr>
<td><strong>Colliders</strong></td>
<td>Colliders to use for interaction with this Interactable (if empty, will use any child Colliders).</td>
</tr>
</tbody>
</table>

Render() (testStringB):

<h1>Table</h1>
<p><strong>Property</strong></p>
<p><strong>Description</strong></p>
<p><strong>Interaction Manager</strong></p>
<p>The <a href="xr-interaction-manager.md">XRInteractionManager</a> that this Interactable will communicate with (will find one if <strong>None</strong>).</p>
<p><strong>Interaction Layer Mask</strong></p>
<p>Allows interaction with Interactors whose <a href="interaction-layers.md">Interaction Layer Mask</a> overlaps with any Layer in this Interaction Layer Mask.</p>
<p><strong>Colliders</strong></p>
<p>Colliders to use for interaction with this Interactable (if empty, will use any child Colliders).</p>

Input markdown:
